I have been messing with my son's nitro sport for a week now, when you first
start it for the day it runs fine. after about 10-15 mins it dies, after that it is extremely hard to start and when it does start it will only run about 10ft
and sounds like it floods out. once started again even if you hold the tires up
and go to full throttle it bogs and wont run correctly. once you let i completely cool down it will fun fine till it warms up and then quits again.
i have checked the fuel lines and the tank no holes or leakes anywhere.
i did notice once it starts acting up it has bubbles in the fuel line, yet acts
like it floods out.

please help i am lost.

thanks shane
