Rotary engine in a snowmobile?? 1970s Johnson (OMC) Phantom revival. Part 1.

I couldn't pass it up... It was missing some ignition components, its dirty as hell, the fuel tank appears to be filled with crude oil and it weighs more than your mom, but I think we can save it! In part 1 we'll look at the ignition system and eliminate the notorious secondary air/throttle valve.
