Hey thanks man! Yea there's no shortage of projects around here.

Yea that old tractor is awesome. It's a Massey I believe, Hydraulic drive, The early version of hydrostatic. It's for sale if you want to come buy it.

Well it's still running and Meaghan loves it. So I'll consider that a win.

Thanks Tomas its still running great.

Not exactly sure what you are asking here but a certain amount of black oil residue will come out of the exhaust of any two stroke, The amount will depend on your mix ratio or oil pump setting depending on if it is oil injected or a pre mix engine.

Some oil injection systems if the pump or cable to the injection system fails they default to a wide open oil injection as a fail safe. So oil and smoke out of your exhaust is a good thing. Versus a clean exhaust with little or no smoke. An oil rich two stroke will run forever where an oil lean two stroke may make more power, but only for a short time before it siezes. two strokes like gas and oil.

The opening in the rings points towards your carburetor. If you put the piston in the other way the ends of the rings can catch the exhaust port and break.
