I bought a 2000 WR400F that had a gunked-up carb from being in storage. It kicked over & ran (although it required the choke to be on or it would die).
We pulled the carb, cleaned it all up, and now it won't start. I've been through the carb twice now; everything's where & how it should be. The only electrical we disconnected were the TPS & the spark plug; those are reconnected.
Fuel is getting pumped into the cylinder.
I put a new spark plug in and it is sparking if I test it outside the cylinder.
If I hold the decomp and kick it with throttle open, I'll get a 'woof' every few kicks (not really what I'd call a backfire, but something's happening).
Help! My leg is getting sore from trying to kick this thing over..
Could it be the CDI is bad (huge coincidence that it would go out while we cleaned the carb). I have a 2001 WR426F that is running fine..could I swap the CDI to see if that might be it???
Any help is appreciated..thanks!
