Hi everyone:
I?m reboring my 1980 115, and have all set to get in pistons and all stuff, but an issue has jumped on me..
The repair shop that has worked on the motor, when cutting the cylinders to .030", didn?t reach all the way to the bottom of the cylinder (not noticed till try to assemble, you can figure my reaction), so now when I?ve tried to assemble, crankshaft does not turn fully cause there?s like 3/16" at the bottom of the cyl. smaller than the rest (cause the cutting tool didn?t reach the bottom). That?s in all 4 cyl....Measure pistons and they all are in specs...identically to the old ones.
Anyway, went back to the shop and they can?t reach further, and there?s no other shop around to do it so...
Ok, they offered me a couple of solutions:
1.- Work the piston skirt with a grinding wheel at the mere bottom in order to get fully down the piston or..
2.- Work them on a lathe and cut the bottom of the piston to make that part smaller to make it fit...
Well guys,need your (as always) great advice and knowledge....what should I do?? any other idea or solution??
