Wow ... 1 1/2 inches off ???
How does that happen ?
Thats has to be the source of the problem.
Have you taken the flywheel off ?
It sounds like somebody took it off and didn't line something up correctly ?
On the Pa's with points ... there are 3 pins that locate the flywheel to a 'holder' ... I have never had it off.. but the holder must be located with a key on the crankshaft?
maybe the key sheared?
or is missing ?
I am surprised it even runs at 1 1/2 inches off.
You could ship me that stuff to inspect and ship back .. thats fine with me .. but I doubt I would find anything .. its so simple.
I would take off the flywheel and that holder and see what the deal is with the key.
... the one odd thing (from the past)... one of those ramp plate dimensions you listed was quirte a bit different from mine wasn't it ? .. there might be 3 different ramp plates maybe.
reading about other peoples problems .. (with the same bike) .. bugs me .. I want to have it in my hands and fix them.
