I need to cut valve seats in my TS and i note that modern engines/valves typically use 3 different degree cutters. Just wondering if someone would be kind enough to clarify if such is needed on my TS, or i can just use the singular 45 degree cutter?
I'm using new valves via LDMCC.
Additionally, I am also installing new J&P pistons and i note various opinions on the forum regarding using "buttons" to retain piston pin vs circlips. I had wondered if the buttons were preferred as they allow piston pin to move/get oil and seemingly the circlips don"t?
I had wondered about ensuring that the piston pin does have some side to side play in it and then use the circlip retainers.
Thoughts appreciated,
Regards
