Hi new hear.!! I bought a 1984 E-Z-GO gas golf cart 2 stroke. It has new carburetor and I also went through it. Its clean and getting gas has spark new spark plug and cranks over but won't start. Wont run on starting fluid or gas if I spray in carburetor it just backfires once in awhile very load out exhaust. Same in forward or reverse. It sounds like a timing problem. I'm not sure what to look for now. Does this golf cart have points or a spark box. Exhaust sounds clear when turning over. Any help would be great.
