I saw video with explain root cause of boucing revs and spark advance is timming belt, question is how to find proper setting of timming? I had try dedicated crankshaft locking pin but it stop piston a little bit after TDC. So i had try another crankshaft locking pin and it stop piston almost in tdc. Then I had try manual set in tdc with my own sensor but after all 3 method I still have the same symptons. To block camshaft i use locking plate in every setting of timming.
I heard that piston should be in tdc and camshaft locked by plate, but why oryginal locking pin have lock piston in diffrent position? Do you or any one on forum notice the same problem?
