Cant start bike

[mxracer2000]

I'll start by saying I've had this 02 KX65 for several years and have done most of the maintenance myself. I ended up having to get the bottom and top end done over the winter and decided to get a shop to put it all back together for me. I installed the motor into the bike and was responsible for putting back the flywheel and stator. Well it all bolted back up fine. I put new gas in the bike, have good spark, the timing is set properly but I cant get it to start at all. I occasionally get a backfire and that's it. I had a reputable shop do the work but I just cant figure out why it wont start. It would start without any issues prior to having the work done.
Any ideas or suggestions?

Are you sure the timing is set right? Getting a spark and having the timing set right are 2 different things.

Is it getting gas? Are the reeds OK?

If the plug is sopping wet, it may be flooded. When was the float valve replaced last? This is supposed to be a yearly replaced item. Keep the fuel off, choke on, throttle wide open and kick. See if it will start that way/flooded procedure? If the plug is dry/a little wet, the rotor may not be properly aligned with the key slot on the crank. Most you can take the rotor nut/washer back off, and see if the slots and key are installed correctly. Vintage Bob

The plug isnt wet, float valve seems fine but hasnt been replaced in a few yrs, timing is lined up where its supposed to be according to the service manual. Im sure the flywheel is lined up with the key.

Are you getting any fuel flow out of, the tank, the carb? The tank does have a filter inside, atop the petcock.

Im definitely getting fuel. I can lay it on its side and fuel will come out of the overflow.
