Hey there.
Thanks for the head up on the 'no-rack' 250 quad.
It did, indeed, have a hand clutch. for that, I thank you.

A friend of mine got a patent on a 3 piece 'rotary' type non-reciprocating engine.

Gotta watch your video again.

Hope all is well.

That reminds me of the 'new' style air conditioner compressor, say, 1982?
What did they call them, ?
Small, rotary, non-up-down piston arrangement.

Very cool video btw.

Hope they make it.
makes sense to me.
