All good things to look for. I have two carbs, both of unknown origin. They came with the two A's I purchased long ago. Both have worked well in the past, but they sat too long with old gas in them and now I'm trying to get them going again. I'm learning as I'm going. thanks

Sorry, I'm referring to the GAV. It doesn't seem to want to seat, nor does it have any effect on the operation of the engine. I start with it out one turn. When I turn it in clockwise, nothing, even when it's bottomed out.

Still messing with carb issues, but making some headway. The issue now is that no matter where I set the air/fuel mixture from inside the cab, there's no difference. Engine still runs even when it's fully closed. The needle valve looks to be in good shape. Perhaps the seat is worn or something...

What's the best Zenith rebuild kit and where do I get it? thanks, rex

By rebuild, I mean that the engine was completely disassembled, parts restored or replaced as needed. Boring, new rings, machining where needed, etc. The only mileage it has so far is driving around the neighborhood trying to get a feel for things. Yes, I understand about not slipping the...

I didn't mean to imply that I have a slipping clutch, I don't. I'm saying that if I were to climb a steep hill, even though in 1st gear, it seems like I would have to slip the clutch to keep the engine from stalling. At one intersection in our neighborhood, I have to go up a rise to make the...

Driving my '30 Model A coupe after a lengthy restoration. A complete engine rebuild with a Bumfield head was part of the project. I'm not sure I'm getting the power out of it I should expect, although I don't know what to expect. As it is, I'm not sure I could get up a steep hill without...

Got both carbs working. One had a sticking float valve and the other had a jet that was completely plugged. Agree that the gas wasn't bad (as in too old). I think both carbs got fouled over time with the ethanol. I do need to run it more often, but I've accumulated too many old cars over the...

I've had this happen at 3 times now. The first time was fixed by replacing the gas. The 2nd time was also fixed by replacing the gas. Admittedly, the first two times, the gas was in there for months, not weeks. The third time, I fixed it with a fresh carb. This time, I cleaned the carb I took...

I took the carb out of my '30 pickup and put it in the coupe. Now it runs fine. Apparently the carb has issues although I can't see anything when I open it up, other than the bowl inlet valve seems to hang up a small percentage of the time.

I've sprayed all the innards of the carb with cleaner and blasted them with air. I have to say that I didn't see any sign of contamination or crud. I did notice that the float valve was a little sticky so I cleaned that the best I could but not convinced I fixed it. Put it back together; same...

It's the ethanol. All gas has it unless you're buying clear gas. US typically has 10% ethanol, which we see in Oregon; UK has moved to 20% and it is wreaking havoc with old cars, destroying fittings, etc.

Thanks everyone for all the excellent advice. I'll try these things with I return home this weekend.

Jim, I've left the gas cap off. I'll try the condenser. Thanks for the carb cleaning info! Dave, I would expect to see crud in the sediment bowl. My assumption has been that the ethanol has been gumming up the carb.

Dave. The engine will run for a few seconds and then die. The first time this happened, I changed the fuel and it fixed the problem. The 2nd time it happened, I changed the fuel, had the carb cleaned out and it fixed it. This is the 3rd or 4th time (slow learner?), same symptoms. I will start...
