Honda Trx250Ex

Hello, i have a honda trx250ex and i cant get it to start. It will turn over all day long but wont start. I have replaced the spark plug, ignition coil, and put in a new carb. I have came to the conclusion that it has to be something about spark but i dont know where to start. I have also changed the main fuse. If anyone knows or has any ideas please let me know. Thanks

carb oem ?, or some stupid china knock-off from ebay or amazon ?. if spark plug isn't firing , then you need to locate the c.d.i., and maybe replace it with a known good working c.d.i. thats oem from honda !. there is no way to bench test c.d.i's. run a test on the stator, pulse generator as well. kill switch clean ?, in the middle ?. neutral light showing on dash ?. if no neutral light ?, it wont' fire the spark plug !.

Also the ignition and everything was ripped out before i purchased it so i turned it off with the kill switch and left it in gear so the neutral light would stay on....this is a little inconvenient right now with trying to work on it

Can anyone tell from the picture if the frame is bent? I replaced lower A Arm and it didn't help. The tire is still leaning outward.Honda Trx250Ex-img_20190324_140058162_1553462048212.jpg Also the machine sits lower on the left side than the right.

you need to get everything back to oem before you go at it blind. avoid all china parts !!!!.

if it won't fire off starting fluid ?, then the timing is off ?, or not enough compression ?.
