My Drifter is running funny. IT will only idle with the choke on. On the road, it's functional with almost no spitting or surging, but at low RPM's it sputters and pops esp. when decelerating. When coming to a stop, I have to pull the choke or it dies. When I do, I feel a surge of power and the engine smooths out for a bit. I noticed, with the air filter off, what seems to be a large volume of fuel coming out of the big needl jet just inside the throat which is moved by the vacuum valve.

As for the symptoms, I replaced spark plugs, checked screen to petcock, made sure fuel tank vent tube was clear, have vacuum at petcock, have fuel to carburetor, cleaned carb wth carb cleaner, so far have run 1 tank of gas with sea foam. It seems to have no power issues, but it will only idle with choke on and I have to gun the throttle a few times and carefully to get it to keep running while I acelerate until I get up to road speed and I can drive normally. I'd almost swear it wa running rich except the choke issue.

Thanks
