Just picked up an 1105 which need quite a bit of tlc. The engine smoked quite well thank you so it now is in pieces in the shop. My question is, it's a Briggs & Stratton vertical shaft model# 253707 type 0171 that I want to put rings or piston and rings in it. The cylinder mics 3.441-3.443. How do I know if this is standard, .01 over, or what? Is there some place on the web that I can find what the dimensions are supposed to be? Thanks, njmj
