I just got this from my brother and he said last summer it ran fine. I tried to get it running and got nothing. No spark, nothing. I re-wired the bike and left out the battery operated items like lights and horn. I now have spark. I also pulled the carb apart and cleaned it. I have fuel flowing as the bowl was full. I put it all back together and tried to start it, I pulled the plug and it was wet with fuel, so I know the fuel is getting to the cylinder, and since I have spark and fuel, it should run, but nothing happens. Any other suggestions.
