Hey guys,
I tried to get help with this on another forum, and I did, but the thread was so inflated, I just wanted to come here and start over, and get some different perspectives (although I know some people from there are here, too).
Long story short; started my TaoTao 49cc CY50-A 2012 (VIP Future Champion) a few nights ago to let it warm up. After about three minutes, it died. That had only happened once before, and before, when I went to restart it, it flooded. So, I took the air filter out, cleaned and dried it, and put it back. No problems for a week. This time, it would not restart and hasn't started since. It did not flood when I repeatedly tried to restart it. I've run plenty of tests which I'll list below:
Got spark against motor, tested with two plugs known good, screw is tight for carb fuel bleed valve (the hose with the metal coil around it), compression is good enough to blow my thumb off of the hole, battery is new and plenty strong and kept up with battery tender; turns over and over. Kick start does no better, just turns it over. Cleaned spark plug, dried it, put it back in, tried to crank a few times and it did come out moist and smelled like fuel. All lines were checked and tested for tears or slipping off. Removed carb and found that during my troubleshooting, I had put the needle back on wrong and bent it, and the diaphragm slot was not lined up; fixed both of those and confirmed they were operating correctly. Didn't have carb cleaner, so just did a light cleaning with wire and alcohol but it was really clean anyway (I expect from regularly using Seafoam). After putting carb back on, no change. Starter fluid did not help; sprayed it liberally up the air intake, behind the filter, on two separate occasions. Still never tried to fire. Also, there is no change in the sound of the engine trying to start when I am full throttle or no throttle.
Notes; when I took carb off, a couple of ounces of fuel poured out. When attempting to start, it never even "almost" starts. I just turns rhythmically over and over. I have a video of it and how it sounds, and photos of the carb while it is out. I replaced the CDI; that didn't help. I'm truly at a loss. On the other forum, they almost had me convinced that it has to be a cracked piston or rings but on this forum, people are suggesting that if it blows your thumb off of the hole, it's got enough compression to run, so if that's the case, it's not a compression problem.
Please tell me there is a miracle worker here; I miss riding my scooter so much! It's driving me crazy, man! Thanks for reading.
