I would have thought this had been covered here, but I can't seem to find anything about it. I recently got a 66cc china motor kit and the main jet is one piece. Seems like I read that the old carbs had a slide needle with 4 grooves, and the newer ones have 5. Mine has 4. So I guess mines the older one? I have never seen a carb that didn't have the main jet that unscrewed from the slide needle jet tube. I haven't started this motor yet, but I am sure I will want to play with this main jets sizes when I do. I would also think that the type I have seen before would interchange, but can't seem to find the slide needle jet tube I need, jets aren't hard to find...checked all the major sellers of these china girls. Anyone with same problem?
