I have a 1973 Suzuki GT185 that died on me one night and wouldn't start back up. Since then I have rebuilt the engine, new seals, gaskets, rings, rebuilt the carb, had a mechanic adjust the floats, replaced the coils, and still the same story. Cranks over and over and won't start. It sounds like it pops when I spray starter fluid in the carb but doesn't seem to help that much. The compression is good, checked with a compression gauge. I see spark coming from the spark plugs. I have no idea what's wrong with this bike. It's getting fuel and spark but it won't start. Maybe I'm missing something, I was hoping someone could help me out.
