Anyone ever mess with a Hit n miss motor?

I dug this thing out from the back of our second shop back in 11th grade. (2004ish)
I cleaned it up, got the oiler working, got the piston and rings free and clean.
I have power coming from the mag, but I can’t tell If I’m actually getting a spark in the chamber.
Also, My intake valve “flutters” I’m not sure if I’m not getting enough air.
This could be normal as I have never seen it run.

My right arm is going to be massive from hand cranking this effing thing.

Never messed with one but always wanted to. Pics?

Have to snap a few later. I had it puffing but my arm cramped up and I had to give up for the day.
I’m about to rig up a PTO attachemt for the tractor.

Took tha mag apart, cleaned it and got it timed last night. I was getting really weak spark if any in the chamber, now it very strong. Doesn’t seem to want to fire gas for some reason. It will pop once on propane.
I can spray gas right at the spark and it wont do anything.
