I picked up a 125 Tao quad. Put a new wiring harness in. Cleaned gas tank and carb. Ran mint for an hour. Started it a few hours later and it was running rough kind of cutting out on acceleration. I noticed some crap in the fuel filter, so I replaced it and cleaned the carb. Bike ran rough still. Replaced carb. with a new one. Ran rough, but I drove it around for a few minutes. It seems like it might be electrical not fuel. Eventually it stalled. I restart it and now it flies??? Stalled after a few minutes and now won't even turn over. What would cause it to cut out? If the timing was off wouldn't it never run right? Help! This thing is driving me nuts!
