hello, i was hoping for some advice.
my kromag (puch engine) didn't have a carb, i found one on a friends bike, now it will run but then die, and it has really low power on a straight-a-way. The plug is all black when i pull it.
is there anyway of telling what carb or jet i need. or is the problem elsewhere.
There are numbers on the carb. what do they mean?
