What I learned today. 42mm cases wont do a 45mm without some clearance to the case.
I felt that catch but would rotate but always a catch.
The 44.3 that came on it afm cylinder too. Didnt catch. I dont see it on my other 42mm I did with 44.3 either. Just clears enough.
So I ordered me some 44.3 rings as I am out and going to clean the other set up and install with new base gasket too. Plug the decomp hole also.
Compared with another 44.3 I had here and exact same everything. Just one has Mahle and other one E. Rest of numbers and letters the same.
So oem piston 44.3 was in afm 44.3 cylinder originally on the 42 early saw.
