I guess they are? I haven't mentioned them once in this thread so i'm not sure what point i'm defending here. They exist in california but I dunno if I'd call them prolific, except in Palo Alto, and I guess SF and Berkely. I guess they're building more than half a million cars a year now? I guess their total global production puts them squarely in line with BMW american sales, based on some cursory searches for US sales

they are extremely prolific. they are all over the place in the bay area, and probably socal too. im down in san jose and sometimes it seems like every other car is one of theirs. that is an exaggeration, but in terms of domestic sedans, they're highly represented. my only point is that i don't buy that nobody here drives american sedans. the roads are flush with them, even if they might not be the majority

anyway i think ive repeated my point several times now, so i will leave it at that unless you have strong feelings to the contrary

How do I spray paint metal? Talking flat black out of a can, not fancy automotive paint.



Once my bumper is done, I will need to paint it. I didn't do the existing paint, but I believe it's primer, then flat black, both out of rattle cans. It's held up fine. The primary goal is to prevent surface rust (SF Bay Area car, so major structural rust won't happen even if left unpainted).

When I repaint it, do I need to strip all the old paint off first, or will the etching primer stick to the old flat black paint? Anything else I should know before I start?

ive been shooting stuff with just the appliance epoxy, without primer, and it seems ok so far. probably others have better opinions. the appliance epoxy only comes in gloss, though, and im not running through as uh harsh of an environment as you are. so im not sure how the durability compares to a more "proper" two part system

I'm sure the 'proper' way to do this is to sandblast it and powder coat it but I would:

  • Clean the part very well with soap and water
  • Give the painted parts a quick sand with fine sandpaper. Not to take it down to metal but just to remove whatever exterior finish is there and to take the hard edge off any rock chips etc
  • Consider blocking off areas (mounting points etc) where you may not want paint - put some painter's tape on there. This is mostly a concern if you have really fine tolerances on the mounting points which I kinda can't imagine given what you're painting.
  • Apply 2 coats of primer at whatever amount of time between coats as it recommends on the cans + 40%.
  • 2-3 coats of whatever rattlecan flat back (tremclad?) paint

Wait wat?
If it isn't something that is rare or needs a proper restoration, I bet Rustoleum black will do a great job keeping rust away and keep it looking black. Really the most important bit is to have the part as clean and free of oils and silicone as possible because no matter what the paint is, this will gently caress up the paint job.

Scuff everything with a red scotch Brite pad. Clean it throughly, then clean it again. I do a final wipe with sprayway glass cleaner and a white paper towel (Scott's in a box) until it comes back still white without anything on it. Primer, paint, and don't disturb it for days. Appliance epoxy in a can is a good recommendation. Hammered finish is good too, provides cover for surface imperfections.

oh yeah, sanity check on this: is the door shut all the way lol

ive had doors kinda stick halfway closed, where the door wont open because the latch isnt engaged far enough for the release to do anything, but it's engaged far enough to hold the door closed. so try shoving the door all the way shut and see if that helps :shrug:

yes i've tried cycling the lock lol, unfortunately not quite *that* stupid of a question. tried it with the key, central locking switch, and just grabbing the nub on the door. latch handles feel great but do nothing, door nub is *way* easier than the other doors to pull up into unlocked position (as if it's disconnected). like 99% sure it's stuck locked

Honda Accord door problem: dumb question, but did you try both the interior and exterior door handles? If a clip connecting the exterior handle to the latch broke, the interior handle should still work. Similarly, did you try manipulating the door lock with the key in the lock cylinder and via the little plunger that goes up and down? If you did all of these actions, did any of them feel odd? Like too easy or much harder than usual?

My 2006 Honda Accord (V6, automatic) suddenly won't start this morning. The starter is going when I turn the key, it just doesn't....take. It is behaving how I would expect if it was out of gas.

No consistent issues before this, although I do think it took an extra second a few times this winter. Last time I "drove" it was pulling it into the garage on Saturday.

Where do I start on troubleshooting?

Blowjob Overtime posted:

Update: clicked to on and heard the hum. Pulled the coil to do the spark test and now realizing I never actually pulled the plug to check for gas smell, which may be moot after the next bit. Put a spare plug on the coil and had my wife turn it over. First time she didn't go very long, and I thought I saw a spark at the end. Had her go again for a five count, and not only did I see spark on the one I was testing, the engine started up. The spark on the spare plug I had connected seemed consistent.

Never closed the loop on this: it was the fuel pump.

I am trying to use a multimeter tach to measure the idle speed of a 1cyl bike but the multimeter doesnt have a 1cyl option, only 3cyl, 4, 6, 8. Can I use the 4 cyl option and just multiply the number by 4?

Sagebrush

It depends on what the multimeter is reading and how your ignition system is configured. Is the meter hooked onto a single spark plug lead? Does the motorcycle have a wasted spark system?

I'd say just put it in 4cyl mode and see if the numbers make any sense. You should have an idea of whether it's idling at closer to 1000 RPM or 2000 RPM, for instance, and if the number seems wrong just halve or double it.

I didn't know wasted spark was a thing... I'm not sure though. The bike is a Honda ct90, so pretty basic 4 stroke. It would make most sense to multiply the number by 4.

I'm having trouble getting the bike to run at idle speed and multiplying by 4 means the bike runs nice at 1800-2000rpm but the nominal idle speed according to the shop manual is 1300. I think it could have something to do with the throttle slide pin.

It certainly could, if for some reason the spark pickup/points/etc ran off the crank instead of the camshaft. Maybe there's an engine like that out there somewhere?

That engine's ignition runs off the camshaft, so it's not a wasted spark. If it won't idle at the lower speed, your pilot jet is probably clogged. When was the last time you flushed the carburetors out, and how long has it been sitting around?

I have a garage door opener. It is a replacement for the original opener that came with the house. I installed it but I didn't mess around with the bank robbery laser beam trip wire sensors. I just used the old ones. After the fact I built some wooden shrouds for the sensors to keep them from getting kicked or otherwise jostled.

Anyway, twice in the last week the opener refused to shut the garage door. Both times were at sunset. When it happened yesterday I tried for several minutes to get the door to close without success. What worked was standing outside the garage and holding a shovel so that the sensor receiving a full blast of sideways sunlight was shaded from the setting sun. The door shut on the first try when I did this.

So what is the easy way to get this to stop? Is there some kind of sunglasses or tinted condom or something I can put on the sensor that will help it shrug off sunlight without disrupting its ability to receive the beam from the other sensor unit?

I think there was some garbage in the main jet where the throttle pin sits and inside the mixture screw holes. I blew both of them out and it seems to run better although I don't want to say perfect, yet. It was idling ok but once I took it around the block and really reved it out a little it seemed to run smoothly at a normal idle speed.

The bike is new to me and although the PO had a garage full of bikes & was some sort of Ford mechanic for a while I don't trust anything until Ive gone through it all.

I did that as a high school project, way back in the day! Accelerometer on the block, A/D, FFT.

Worked great at idle, but above that, every piece of poo poo bolted to the engine starts buzzing at its own resonant frequency and you get a bunch of garbage. And that's when parked in neutral; I'm sure it's worse if you're actually driving. More sophisticated signal processing should help, but it's not an obviously simple problem.

Short term, most door openers will let you force them to close if you hold the wall button (you'll need to hold it the entire time it's closing until it's fully closed, otherwise it'll re-open). Won't be able to do it with the remote.

I bought this vehicle used from a dealership. I've had regular tire rotations/replacements, brake work when needed, and oil changes every time the light comes on. The folks at Grease Monkey top off fluids and check for whatever poo poo they check for and it always comes back OK. I've replaced the throttle body unit and power steering pump when those failed.

But I've done nothing else to upkeep the car. I don't know much about cars and I didn't really have any sort of maintenance schedule. Currently it's a bit slow to turn over but hasn't failed to do so yet and the transmission (I think?) has started to get a bit "lurchy," especially at lower RPM. Otherwise it works great.

Basically I'd like to get some preventative maintenance done but I have no idea what I should ask for. I don't want to get taken advantage of, but I also understand it won't be cheap. I'd really appreciate any advice with regards to what I should have done and a rough estimate of what I might be looking at, which will be helpful when I talk to my local mechaincs.

If you have the owner's manual, there should be a table in the back of recommended maintenance schedules. I'm generally in the "don't fix it before it breaks" camp with most stuff that's not consumables.

You probably have the original battery, which would be pretty crusty by now and would explain the slow turnover. You may want to price out a replacement before it dies so you're prepared for it.

Personally, I don't know that I'd go writing off the car just yet, but I don't know its full history. It might be a good time to sell, but it's also a terrible time to buy.

So for the rest, there is a car buying thread over in Ask/Tell: https://forums.somethingawful.com/showthread.php?threadid=3213538

In general though, I suspect they'd recommend against a short-term purchase, and especially not a BMW of unknown origins. A more budget-friendly car of some sort maybe would be looked upon more kindly, but still you're liable to spend many more dollars than you would if you kept your car until you were able to get something you would stick with long-term. I can't imagine the GR Corolla is going to be something you can easily buy once it makes it over here either, but I could be totally wrong in my assessment.


Just wanted to follow up on that bolded comment. I did sell the RS for an E91 of dubious reliability 2 weeks ago. The dealer has since called me back asking if I had any clutch issues with the car, because now the pedal is sticking to the floor [again] after I had the master cylinder replaced 500 miles ago. I reminded him that when I traded it in, I mentioned replacing the clutch and numerous other things :v:
