Growing up in the early 70's there was a kid on our street that had a boonie bike. I was so friggin jealous! Yours looks awesome! Now I'm jealous of yours lol

King of all side poppers!!!

Maybe the intake manifold from a vertical shaft would fit. Or this odd ball, not sure what this came on...

Me too! Sure is cool looking.

Side popper, with a HS4 cam in it. The exhaust port will be the intake port, and you fab up a cool looking intake/carb facing forward. Just to be different.

You are the master of Tecs!!!

Tig weld all the bolt holes closed, drill to correct pattern. Then reface for flatness. Yeah I know, not worth it. But that head is used on engines that make pretty good hp for a stock flat head.

What engine did you use to order a head? The head I had in the pic, found in a metal scrap pile, with what appeared to be a Tec block..

I remember some of the Craftsman edgers had a remote paper air filter mounted up high on the handle.

When I was a kid back in the 70's I tried advancing & retarding cam timing by one tooth. Started and ran, but not much difference from stock. Also tried the lighter flywheel from a rotary lawn mower. That made a difference in acceleration, but really hard to get running.

Good thought!! I agree, and without any marks on the valve, had to be the old rope trick.

If water was sucked in, the connecting rod would bend or break first. I bet the valve was stuck open, and someone tried to free it, tapping with a hammer & screw driver through the spark plug hole.

Or the magnets are out of time with the key way if it's not the correct flywheel.

Always cool to watch them fire up!
