He actually took a poo poo down the plug hole after getting that out to teach the motor a lesson. Metal shavings should get collected in that.

How in gently caress's name did you get the broken one out? A few metal shavings won't hurt anything... Just gets blown out the exhaust into your catalytic converter

A few more heat/quench cycles later, a better quality ez-out pulled the remains of the plug right out. Faster Blaster posted:
Once I got the remains of the plug out, I rotated the piston down a bit to make some space, sprayed in some WD-40 and snaked a hose in and vacuumed around. Didn't see any metal residue in the hose. Stuck an endoscope into the piston and couldn't see any shavings.

There's a certain point in a project where you honestly don't give a poo poo because after 20 hours of loving around and it destroying every muscle in your body along with constant thoughts of "maybe I can try this..." once succeeded you stand back in pride that you accomplished the goal. This one was drat impressive. And never underestimate the use of a dremel in these situations.

I'm slightly surprised that he, of all people, would forget that a carb will squirt / leak fuel any time it has pressure.

Just another reason to actually check when you have something that has two settings and the manual claims it is set up in a certain way. Not really automotive related, but I bought an e-SATA card so I could hook up an external harddrive and I thought it didn't work at all. Turned out it came from the factory with the jumpers set to using the internal SATA ports, not the external e-SATA ports.

It's just mixing old with new/customizing something type of thing. Old carby cars, especially n/a ones I owned) didn't have a pressure regulator and even if an electric pump the fuel pump was low pressure. Even back in the day when I added a holley blue the regulator was on the supply line to limit the pressure on the needle and seat IIRC. Add forced induction then you are mixing well known old carby stuff with EFI fuel pumps and regulators so you need to work extra poo poo out as you're making a hybrid.

My brother's best friend's old ('60s, first-gen) Ford Bronco has a similar problem with the spraying fuel out and catching fire. It's not the carb, he's tried two and rebuilt both twice (and I rebuilt the second carb myself before my brother donated it to the project, so I know it was good). The (new, the one the parts store said was correct for the engine) mechanical fuel pump must be making too much pressure, right? That's what I and my brother think, but buddy says it can't be possible. Do fuel pumps that hang off the side of the block driven by the cam come in FI-pressure versions? Edit: should I be good and convince him he's wrong/give him y'alls suggestions on what to do, or be evil and make a lowball offer to buy it off him and then fix it myself?

The issue isn't just the regulator, it's pressurizing the fuel system of a non-running engine with a carb. When he was leak testing, he flooded the engine out because he had the pump running and the engine not. A mechanical pump can't do anything with the engine off, and unless it's broken, fuel injection on a shut off engine will actually stay shut.

That's what I and my brother think, but buddy says it can't be possible. Do fuel pumps that hang off the side of the block driven by the cam come in FI-pressure versions? I have limited experience with mechanical fuel pumps, but in the once instance where I had to replace one (Mercruiser engine - basically a straight-4 in a ski boat) I and my brother spent the better part of a day tearing our hair out over the fact that the newly-rebuilt carburetor kept flooding out within 30-45 seconds of engine start. Thought something had gone sideways with the rebuild, took it apart, couldn't find anything wrong. Finally realized that the old pump gasket that we had scraped off of the side of the block was actually two gaskets held together with gasket sealer. Turns out that the "arm" of the pump was getting pushed too far by the rotation of the crankshaft (because of the lack of shims) and thus generating a lot more pressure than needed. We experimented and ended up with a stacked set of gaskets which held the fuel pump out from the block almost 1/4", which generated enough pressure to feed properly, but not enough to overwhelm the carb. TLDR: try shimming out the fuel pump on the Bronco to reduce the the amount of pressure the pump generates.

Still I think a needle valve at a low pressure would keep the fuel out, right? I’ve had gunk keep mine from closing and it floods the engine in a hurry with a mechanical pump while running. I’m not sure what kind of pump or fuel system he was using but you can use an electric pump with a carb without flooding the engine with the key on and engine off.

Any auto parts store with a chrome garbage SBC 350 with 4.20e69 horsepower rack/aisle will have a $25-ish knob style regulator. Just use one of those, they usually max out at about 6psi.

HMF, in a mine! The WA 900, a 100+ton articulating loader, with a 13 cubic metre bucket.  They, um...they're supposed to have 4 wheels. So it turns out, that when the manufacturer says "use this specific oil in the axles," and somebody else says "I guess, but this other stuff saves us $500 per oil change," then mechanical parts fail horribly.  These used to be brakes. Then they were smoke machines for a while, and now they're twisted pieces of metal. For reference, the whole stack should look like the bottom half.  Uh...none of it should look like this...Those should all be perfectly flat.  Those splines should go all the way down the housing.  And there definitely shouldn't be metal flakes this size in the axle oil.  This is a different brake that didn't machine away its splines, but all the gunk you can see is magnetic, and typical of what was inside every gear and bearing. So complete front axle rebuild: new bearings, brakes, and differential. Plus hundreds of hours of labour. Nevermind the rear axle, which also had more metal in the oil than is strictly necessary, which they are electing to do nothing about at this time because it still works normally (we will be back in 6 months to do the same job when they run it to failure as well). The ultimate answer to the question of "Why are we paying this much for manufacturer oil when Chevron is so much cheaper?" Did I mention they did this to two of their machines? And both failed at the same time, in the same way, (presumably) for the same reason? And they were the two main production loaders for this quarry? Total cost, including downtime: idk probably over a million All to save a few grand on maintenance.
