Well, looks as if someone has had the top half apart, and was crazy with the permatex, you don't or should not use that on base gaskets or head gaskets. I would clean all the permatex off, get a gasket set, rings, and do rebuild top half as long as you had no bottom half noise or issues. Or, do a complete rebuild. Depends on your budget.

If it has low compression, that's a big part of the puzzle there. The cylinder needs checked to see if it's still in spec for the piston. If it's out, get it bored and honed to match a new oversized piston. NO Chinese eBay cylinder kits...they are garbage.

That gasket material is going to need cleaned off....and when you put new on, use cometic or OEM base gaskets. They are the only 2 proven to work.

Yea i cleaned all that off dont know why they used that either but i put on new gasket set ..it looks like the tors been removed by wires but it still on carb..and hechad it turned all the way counterclockwise..so i removed harness for now ..but when i get spark do it have to be a bright spark on spark plug tester or just as long as u get a spark its ok.

just make sure you check (inspect) all parts if your reusing any old parts ( wrist pin, bearings, etc, and use new c- clips that holds the wrist pin in piston. Wrist pins do wear and there is needle bearings that slide into the top of the connecting rod as well. If one of those c-clips would happen to come out, you won't be happy.

Yep, that's what I'm talking about, that sucks. I buy motorcycles and rebuild them for lil extra guy stuff money, I never never ever reuse any old parts out of a motor like wrist pins or c-clips
