Chinese 150cc ATV no start issue

This four wheeler was brought to me with a no start issue. The owner had replaced the key switch. Going through I noticed that the fuse was blown. Since I did not a have a glass fuse, I replaced the holder with a spade type, but it kept blowing when the key was turn to on. Looking at the wiring of the replacement key switch, I noticed that the colors were off. I repined the wires and the fuse no longer blew. The engine would start, but not run, so I attempted to clean the carb. it was a sealed unit, I attempted to drill out the pins, but too to much time to line up perfectly. I replaced with a matching carb I found on Amazon and now starts and runs great.

We have a xpro 125. Was working fine since we got it july 21. Rode one day in the rain for 2 mins and put it in shed and now wont start 🙄 tried cleaning carburetor, new gas and still nothing. Kicks on but wont start. Buying a new carb tomorrow but if that doesnt works, what else can it be??

It is probably the carb. If you can take the bowl off and clean thought-out , it may work. but I have had good luck with cheap carbs from Amazon.

@@mrfixit4211 we tried EVERYTHING, new carb, the top vaules were off so he set them to the right setting. Battery charge, getting spark and STILL no turn over. Do u have a email where I can send you a video of our problem?? Next step is to test air compression, no fuel lines clogged so we know the gas is getting through. Got it from xpro and it's no refunding

@@taramassey4768 No start or turn over? Since you indicate that you have verified basic items, last thing would be to verify timing..
