I have one of those mini harley choppers its either a apc or electra or xscooter. Do not know! I figured out the electrical since no key switch or fuse or starter solinoid. I replaced the coil that was shot. Literally fried plastic melted and wiring. Carb was leaking. Rebuilt carb put new gaskets on intake and carb. Its getting gas and spark. I get a one poof thats it evan with starter fluid the oil gas mix is perfect fresh. I diconnected the kill wiring on it just in case new spark plug gapped along with coil air gap proper. Only thing im thinking is compression loss. It sat for 3 yrs so thinking gaskets cracked or rust scoring cylinder or rings bad. Previous owner said it ran before he hacked it it looks like 40 cc to 49 cc 2 stroke chinese made red and black plastics. Any help or suggestions would help greatly.
