Uh-oh...flooding

Good deal.

I did some testing this afternoon. I went ahead and pulled off the airhorn of the carb. I found that the bowl vent valve was there, but installed the wrong direction, so I fixed that.

The floats were just barely a little high so I lowered them just a bit.Everything else inside looked fine.

I rechecked my lines at the canister just to be sure I had them connected correctly, and they are, but...I tried to blow back through the vent line to the tank, and couldn't. I removed the gas cap and tried again, and could not. Maybe that's normal, I'm not sure.

I let it run and warm up to temp, and a little over, with it in gear, then let it heat soak about 45 minutes with the gas cap OFF to take a tank pressurization issue out of the equation, and there was no hint of fuel out of the carb and it started and ran fine.

I did notice that the carb is pretty HOT after it heat soaks, even with the thick spacer under it.

Returning to the tank venting....the other day I had the fuel sender out to see why it wasn't working, and when I put it back in, fuel started siphoning out of the output all by itself as I tightened the lock ring down.

I got out from under and loosened the cap and got a whooosh. This is probably nothing..I would think if the tank was actually sealed tight the engine would quit due to not being able to pull gas up.

The car is still cooling down so I'll give it an hour and see if I get anything. If not then I'll drive it around in the heat of the day and test it that way.

I'll insulate those lines. Speaking of that issue, between my brother and I, we have 3 running Mopar V8s currently and all of them react differently to the hot weather starting.

Mine you know about. My brother's '83 D150 w/ tired 318 and BBD spins and spins before it catches when hot. His '73 Dart Sport w/ 440 and a Holley 4bbl starts and stalls at least twice on heat soaked starts. It doesn't flood, it just starves until it gets gas back in the carb.
