Lawn Boy Duraforce 2 cycle

I just had the head on my duraforces mower milled slightly more than it was plus got ride of head gasket and used copper spray a gasket. That would do good on a mini bike lol. 160 psi of compression. How long till the rod breaks is the only question now

Yes, I'll set the squish while they're apart for seals and reed mods. Likely eliminate the head gaskets, if that works out for quench distance.
I messed with a spare block, raised and widened the exhaust port. I need to mount a degree wheel and verify port timing before cutting a good block.
