I was flabergasted , it has a circular counterweight , no attempt to balance and a really thick piston , it ran OK , but I will try a rebuild , and hope for the best , now can you make a piston from very hard wood ?
What is the ignition temperature of Jarrah
The ignition temperature of Jarrah hard wood is 425ºC but what wood worry me more is its coefficient of friction outside of a low temperature heavily greased environment.
Anyway the full circle crank web can be dealt with very easily by scalloping out the metal either side of the crank pin and I am wondering if simply shortening the piston skirt for lightening might work, sub piston induction aside.
