OK choke is not the problem I don't think. When I crank the truck it runs fine for about 20 seconds. Then it starts to misfire and stumble like crazy. There is definitely gas coming out of the tail pipe. Another thing I seen this morning is gas dripping from the fresh air intake from the bottom of a charcoal canister. Pretty fast dripping. I have a weber so I I though my canisters didn't have much purpose now. Keep in mind that I have put a 1000 miles exactly how it sits right now without a problem. I haven't changed anything. I'm stumped.

If you have fuel in your charcoal canister you have a fuel pump problem. Probably a ruptured diaphragm.

Thought about that too, most forums say I would have the fuel lines crossed somewhere, but after a year and over 1000 miles driven I'd think that would show its face a lot sooner. I'll check out the fuel pump this evening.

I will add that my fuel pump is mechanical under the hood. Not inside the tank. And that I think a pump problem would make it starve for gas, not get to much. For sure gas coming from exhaust. No black smoke though.

You could have a plethora of problems. Webers have weak needles and seats, it's easy for anything over 4-5psi to just push fuel past them.

The fuel pump, line routing, filters and carb can all play a part in this kind of problem. Good luck.
