Yes Bob, When I think about it, I have had a power torque engine running, looking through a gap in the head gasket at the flame inside the cylinder.
I even went & grabbed the misus to show her that one, she just though I was crazy.

Suzuki has no head gasket.

But the seals are on the other side of the piston, so as the piston moves forward there should be high pressure in combustion chamber & a vacuum in the crankcase to draw in fuel.

This would have to affect starting.

I dont have a parts list, just one I have made up over time.
Try the Torro web site in the US, they have a manual but no part no.
Also try the australian site "spare parts online" they have suzuki bits.
