My Jawa 210 sport will go right up to 15mph, then quit accelerating.
I have cleaned the carb,
I have changed the spark plug,
(CDI ignition so no points to need replacement or adjustment)
I thought that the exhaust was restricting me, but this is not the case.
It ran fine last summer, and I drained everything over the winter months.
What could be holding me back??
Does it sound like lack of compression? Do I need new rings? wouldn't I have to break them in?
All help is appreciated,
