valve lapping
I have a 4 cycle marathon 295cc. Cylinder head is in good shape. Im replacing valves and wonder if I can just lap the valves, or will I need to cut the valve seats. The price seems to be high for a cutter tool

Re: valve lapping
You could try it and see what pattern you get. If it's not too wide it will probably be okay.

Re: valve lapping
yes just lap them! The seats are hard & the exhaust valves are to but not the intake valves those are soft and go first.

Re: valve lapping
all replacement valves should be harden. also it wasn't to many years that they used the non harden valves in those engines. something like 94-00. i'm not sure those are the exact years but it's real close
