1948 JC Higgins Board Track

[SHEW SHOW]

I appreciate your input Royale.
I also messaged CulverCityClassic and he said that with the 50cc hi compression head it would likely have to run 100-100+ octane.
Since I'm only out to have fun with this thing, a trip to the local race shop each week isn't for me.

Thanks again,
SS

I drilled my Puch 70cc HiHi comp to the 8mm on center and even though the off set is there it made for a snug fit insuring that the head stays center on top of the cylinder.
