Just another thought ...... how long ago were they done ?

I couldn't get a good picture and laying the valve on the table it didn't rock. I have 4 short seasons and about 45 hours on it. He did put stainless intake valves in it this time i just didn't want it to happen again.

Cant really tell anything by that picture but if the engine was built 4 years ago and you only have 45 hours on it I was wondering if the fuel is old and turning to glue and holding the intakes open ? I have seen it more times lately than I can count. Or if the fuel is getting bad enough it can cause detonation which will also affect the valves.

Just thinking out loud

BillK you obviously dont know what you`re talking about .
I filled up with bad gas (basically laquer) and 5 minutes later my intake valve didnt intake so much anymore but when i posted the pic I was told bad gas doesnt do that , Im wrong and its something else .. just a coincidence.lol
