Looks like it has the original muffler,which is a hard to find piece these days.The fenders would make it a 66 if they are correct. The floor boards are interesting.
Ok, finally on the ipad and the pictures are,big enough to see.
Definitely a Tecumseh, everything the guys pointed out is right.
If the fenders and engine are OEM, it should have points... If it has points, worst case scenario, you convert it to battery ignition, it those mags are pretty robust and the issue (if it's sparkless) is more likely points-condenser than serious.
I've had two of these OEM mufflers. They aren't much for muffling but they are neat to have. Only blessing is the noise is kinda blown forward.
