Camshaft question

Mon Nov 05, 2012 8:40 pm

I bought a blown 301 Kohler (12 hp.). It was worn to bad so I had it bored to a 321 (14 hp.). The piston had exploded and I noticed the tang on the camshaft was bent and would never help with compression release. I bent it back but was wondering how high it should stick up to release comp.
