Just got my 172 gas block back from machine shop. Installed crank,cam, flyweel, and clutch. Put on tractor then tried to install
pistons. The pistons are marked STD but they are so tight in the bores that I can't push in. Took rings off and tried every bore
upside down. Pistons drop in easy until reaching the skirt which stops entrance. Kit came from this site so I trusted it's worth.
Is my only recourse to take block to machine shop to enlarge bore? After all i've done and paid, it kind of gets me grouchy to
undo so much. Is it possible to hone out a fit this tight? Has anyone gotten sleeves too tight for the pistons?
Durn!!!
