oversize valve seat OD size?
« on: January 01, 2016, 08:59:31 pm »
Happy New Year everyone.

Does anyone know how much bigger than stock the oversize valve seats that Briggs offers for the 42 opposed is? I have one that came loose and beat up the seat bore a bit. It's .023-.025 larger than the seat. I don't know if I should order the oversize seat or buy an aftermarket one and bore the picket to fit it?

Cheers,

Rikk

Take it to an automotive machine shop,they can use a cutter to bore the seat larger and put a new seat in,seats come in all sizes and are installed with .005" press fit
