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

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?
