Just recently bought an 88 RC le150 and had to have the carburetor redone due to a dirtdobber nest inside of it. It was not too big a deal and fortunatley did not cost an arm and leg. For a good solid month now it has been running like a top, with a slight desire to get hot (texas weather). Now I have come upon a problem that seems to be carb related. When I start her up in the morning, I have the same success as I was when it was running fine. But the idle seems rough. It has a sputter-like pattern to it and if I attempt to put it into drive or reverse, there is a major hesitation in acceleration. It does not necissarily die, it just remains idling choppy and hardly budges when gas is applied. Now the odd thing is, if I turn her off and come back in 30 mins or 45, she starts normal and idles fine, as well as drives fine. This problem started occuring a week or so ago. Every once in a while i get a small amount of hesitation at stop and go situations, but it hardly noticable once the major bout in the earlier portion of the day is over. I am not too familiar with carbs, but from the symptoms I am only guessing this is the problem. Luckily I DO have a lifetime waranty on the maintanance of the carb. I heard that Q-Jet carbs tend to flood easy, yet lately I have not really been pumping the gas to get her started too much, so I'm not sure. Any suggestions would be muchly appreciated.
