[QUOTE="atafonso, post: 610878, member: 23592"] Laping would be the first thing to do, but after laping the valves could still be leaking. Sometimes the heat moves things and the seats can distort, so laping only will not do the trick. The seat would have to be reground or re cut. You can test a valve leak by placing fuel inside the port and watching the chamber for any fuel signs, dead easy😉 Abel [/QUOTE]
