I just got my first motor put on my beach cruiser and decided to kill some time at work. My motor took forever to finally get it started then ran great for 20 or so miles. I have a 66cc SD stinger by the way. Now the bike won't even start. No kill switch connected. I'm flooding the engine half the time, and not getting any fuel the other half of the time. Have my NT carb apart every day, and moved the c clip to every notch on the pin. Replaced the plug with an NGK, and I think I'm getting a weak spark. Most of the time I can't even get it to start on starting fluid. Any advice would be greatly appreciated. I bought another bike and engine kit, but want to get this one running before I start a new project.
