OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Briggs & Stratton Engines B&S 12.5 HP I/C Quiet, exhaust valve retainer.

Gadge, thanks for looking those part no.s and rings up.

Could I use my drill hone to hone it out oversize? Sounds like a lot of honing, I think I would like to practice that on a small engine first.

I have done some more work on the bore with my battery drill on 1st speed, here are some shots.




With a worn bore plus my honing could I go up a ring size?

The valves are lapped and came up well, here is how I put them in, not having the compressor tool.




Just have to wait for gasket kit and rings now.
