GnarlyCharlie4u posted:no but then there was something seriously wrong with mine because it would not idle normally. it just revved to high heaven. Those usually have an air vane governor, so the air being pushed by the flywheel pushes on a little arm connected to the carb. The faster the engine goes, the more it pushes the air vane so it feeds less fuel and keeps the RPMs stable and limited. If they get sticky or gunked up then the engine will rev wildly or stall under load.

So you have to push while its high, then wait, push while its high, wait, etc.

If you've got a surge with an airvane, you need to clean the jet or otherwise enlarge it.

That sucks. While I was cleaning the head and block, I noticed that the hone is non-existent on the Briggs. Are the engines about the same as a car engine? By that I mean should there be a cross-hatch in the cylinder chamber? The Mower itself is about 10 years old, so would I just buy a ring kit and hone it the same way I do a car?

I was "gifted" a mower that would barely run and stall in grass. It had a foam sponge air filter that was clogged with oil and sand and a carb that was just as filthy. I didn't care if it worked or not so I took the filter off and pulled the starter. It idles lovely as hell. I didn't care if the mower ran or not so I poured some sea foam right down the intake. The whole mower lurched as it fired good for the first time in who knows how long, so I keep dumping it in. Engine dies when I stop feeding it sea foam. So, I cleaned out the air filter and mowed the yard on a mixture of 50% sea foam and gas. It only smoked for about half the yard. Smoked is a polite way to put it; the thick white cloud that came out of that thing drifted across my neighbor's yard before dissipating. tl;dr: got a free mower that was so neglected that sea foam kept it from bogging down

Whatever happened, it was more than just a curb/hump/highside problem. That front suspension collapsed. If it where a normal highside, both front and rear suspension would be fully extended or nearly so.

Some people are suggesting it was a protection mechanism that got triggered. I can't imagine a scenario where turning turtle is the best protection however. I'm down with the pneumatic suspension idea myself.

here's the shortblock from our race car after sunday morning: and here's something we just pulled apart: guy had the motor built, about 1000 miles later a cam gear broke and bent all the valves. The cam gears on a subaru are composite plastic so if you drop or crack one they can explode sometimes.

When I went to grease monkey school we had one of those with the phenolic gears that had grenaded in the tear down room and I heard it was a minor issue, but at least with them it was non intereence, but that may be anecdotal.

Lowclock posted:At least some of the old chevy straight 6s (250 etc) had phenolic timing gears, and I never had any issues with mine or heard about it being a problem. Maybe it's not the same kind of resin? The original 350 in my truck had one. Sometime in the late '80s it decided that it no longer liked the camshaft and wished to separate. Took the timing cover, timing chain, some pushrods, and some exhaust valves with it. Timing belts I don't mind as long as they have a sane replacement process and interval, especially on non-interference engines. Plastic has no business in an engine's valve timing system, especially on an interference engine.

I'm not fond of timing belts, but after using them on TDIs and volkswagen TDs, I have not minded them. Most of them last forever and as long as you get a quality timing belt, you won't have issues. I fully agree though, plastic does not belong in the engine's critical timing system

The Iron Duke had plastic timing gears, but I'm pretty sure they didn't use a chain. Most of the time though, it's not that big of a deal, since plenty of people have gone 250-300k miles on the original timing set before it gave up. Luckily they're non-interference, so you just replace the set, reset the timing and you're good. Replacements are, shockingly, steel, so barring some sort of oil starvation or submarine captain, the Duke is ready to go another million or so.

The protection hypothesis(for Obama's limo) is sound because it could be there to keep anyone from mucking about with the underside of the car. Some sort of laser-grid or something? a touch sensor? That way when joe schmoe terrorist tries to cut the prez's brake lines all he gets is a broken arm trapped under one sweet caddy.

Joe shmoe terrorist isnt going to be getting anywhere near a presidential limo when its parked. I would agree what some sort of protective mechanism was set off, pulling the wheels into the arches. But if you think there are exposed hydraulic lines running underneath a car that supposed to keep driving after being hit by a bomb, that is false. It would be interesting to see if the rear wheels retracted as well.

A Kia is too good for him...hell, a riding lawnmower is too good for him. HEY GENIUS: drat near every modern car manufacturer has made an interference engine with a timing belt. Guess you'd better sue all of them too! What kind of stupid entitled oval office do you have to be to think that a timing belt every 60k and plugs every 15k isn't reasonable maintenance? Holy hell, just a few decades ago you'd be rebuilding the engine at 60k. Not to mention that looks more like detonation damage than valves and pistons meeting. I guess that's kinda moot now though. Sorry, people like that just really push all the wrong buttons with me.

Somebody else put in a new timing belt and got the timing wrong to begin with and coupled with an old tensioner it must've gone even more off when, according to the owner, it backfired one day when he went to start it. I'm amazed he was able to drive it to the shop at all.
