Hi guys, this is the first engine I've ever worked on ( I have next to no knowledge on these things ) - learning though!
So my 78 maxi died while I was riding it last summer. Currently I have spark and it seems like I'm getting fuel since I can get the carb to overflow but seems like my compression is very low. I used a new compression tester and at first thought it was broken, but after a few kicks it read like 15psi. My brother said he could feel air with the thumb test though. Maybe it's noteworthy that when you kick it it doesn't make that chug chug sound they make when they're trying to start, just a whirring kind of sound.
I recently took the cylinders off and replaced the piston/rings, as well as the base, head, exhaust and carb fitting gaskets. Also put in a new spark plug and new carburetor (I didn't set the gap on the spark plug or really do anything to the carb besides install the throttle cable).
My theory right now is that my gaskets aren't installed well enough. I did my best to remove the old ones with carb cleaner and a razor blade but didn't sand it, just slapped the new ones on with really really slight bits of old material still on there.
I'm also not 100% confident that I rewired it correctly (when I took the throttle off I accidentally disconnected the two wires coming out of it, may have switched them up when I reconnected them), could that be the issue?
Any help is hugely appreciated I've been gradually working on this for a couple months now and just want to get it running before it gets too nice outside!
