I removed the carb and one of the two jets was clogged. I cleaned it and reassembled it. It runs well now.
As many may already know, I need to understand the mechanism. I have little experience with twins. My experience with retarded fuel delivery has presented as surging, no start, etc. My guess is that with a twin, the symptoms would present differently?
My assumption is that because there are two jets, two cylinders, and two pick-up tubes, while one may be deficient, the other is rocking, which may lead to a different behavior? Or maybe it can happen in a single cylinder and I just haven't run into it yet.
Is the popping happening in the cylinder with the lean mixture or the one with the proper mixture?...assuming that this was the problem. Which, at this point, seems to be the case since it's running so well now.
Thanks.
