I recently did the hot cam swap and cleaned the carb out on my 2000 yz426. After putting everything back together I can't get it to fire. It seems like it isn't getting fuel. I just keep kicking and kicking and I get nothing. Doesn't even sound like it wants to start. before this work it ran 100% fine, it just wouldn't idle right(why I cleaned the car), but trail running it had no problems as long as you didn't allow it to idle for more than a few seconds. I do have spark. That is one thing I am certain of. I pulled the plug and placed it in the boot. Closed the garage door and could see a good spark and it is a new plug also. Any one have any tips or know what I'm missing here?
