I was asked to work on this one. It was bought with a China Carb in it, and a aftermarket carb boot to the intake.
I have cleaned and been thru the carb dozens of times. Put the correct jets in it (not the unmarked chinese ones), i have gone up and down with the mixture screw.

It idles like a champ, but as soon as you hit the throttle it pops. if you can get past the pop, it runs at the top.
But the pop is so bad it will blow the carb out of the boot sometimes.
I'm going to get a Can Am intake boot, but does anyone have any ideas

Thanks
