Anyone know what would cause a 2 stroke chrysler to hiccup once in a
while during idle? It runs fine when cruising around, but sometimes
during idle it sounds like it misses for a brief second, like it wants
to die and then goes back to chugging away.

I had a 4 stroke 200cc Yamaha dirtbike that did the same thing. Could
never figure it out. My gut feeling is that it is a carb
issue....maybe time to rebuild them?
