back to my fouled plug /idle problem

Anonymous-0 · Oct 2, 2008

I put the correct heat range plug in, took the carb apart as much as I could and blew it out with carb cleaner. Moved an e clip on a rod that was set at the richest setting, put everything back and it's a little better. Still a little smokey and seems to load up periodically. Could it be that the carb is just shot? I can't figure out how the choke works (doesn't have a butterfly like I'm used to seeing, maybe something like glennster said with the small hole on the intake side, but I don't really see that either )but there is a difference when I move the lever.
Is there such thing as a universal carb for these things? The replacement is hard to find and is real expensive, repair parts are not available, and a new one would just get me a new carb that I don't understand.
Think a new carb will fix my problem?
Thanks, Dave

The choke butterfly is not on these carbs. The enrichener circuit is a plunger that picks off an opening and allows engine vacuum to pull fuel directly from the fuel bowl into the venturi with the throttle slide closed. There MUST be a bit of "slack" in the enrichener cable when the lever or knob is down or pushed in whatever the case, If the plunger is at all off its seat when the slide is down enough to have Vacuum in the carb it will pull raw fuel up and directly into the intake, generally there is a threaded adjuster to allow the "slack " to be obtained. Do not overlook a worn needle and seat where the fuel enters the carb, high mileage units can have wear and cause fuel to leak by.
