So I'm working on a yz 426. It just had a top end done (not by me) I just got into it this morning with the expectation of rebuilding accelerator pump and firing it up.
First I had to fight the carb, the o ring on the seat was shot.
Then I got it to fire but as soon as you turn off the choke or touch the throttle it dies. Been thru the carb 2 times. I'm pretty sure its not carb related.
Is it possible the woodruff key was put in backwards and it's retarding the timing too much.
I don't think it's out of time because I have compression and it will run.
