2001 Polaris 500 scrambler boggs down

[Inovermyhead]

My sons scrambler was running fine till he rolled it, now it will start and idle but when you give it throttle it Boggs down, if you nail the throttle it will die. Sounds like it’s restricted or backfiring thru the carb. Any suggestions?

Pull the  carb and clean it .  It is  quite possible when he rolled it  some dirt  that  was in the float bowl  was shaken  loose  and is now  plugging  a  jet.  Bogging,  quitting   when "nailing it"   and backfires are  symptoms   of too  lean  or  no fuel  flow  on open  throttle.

Ive pulled it and cleaned it twice now, still same results, chases all the wires down, still same, what about the fuel pump? There are 3 hoses 1) inlet 2) outlet, the hose on the top of the pump doesn’t have anything coming thru it

Take a fuel line and run the gas directly into the carb as to Bypass the fuel pump. If it runs fine then you know there is a problem with the pump. You can try to hit the fuel pump with something as you try to start it. It often gets the pump spinning.
