ebay is a good place for decals . another member here makes and sells on there , silensmessor i think is his ebay name . just type in scott bonnar decals and it should be there .
might like to pop off the flywheel and clean n reset the points before you pull it down just to be sure , or just replace the coil with a later model , then no more points to worry you .

also service the starter clutch while you have off the cover then its done and wont squeal
