Default Throttle hangs when driving please help

when is just sitting there it seems to work fine but when I go to drive it as soon as I get to on the ground with it, it hangs wide open. I have even got someone to hold it across the track from me and make sure everything is working fine when I hit the throttle and then as soon as they put it down on the ground and I hit the gas it hangs up. can anyone help me on this please

Check your linkage and make sure its pulling the throttle open straight. If it is pulling at an angle it can get hung up inside the carb body. It must be smooth.

Also check that nothing is fowling the return of the throttle linkage.. Body, fuel line, airfilter etc... Not enough spring tension...

Ya. Spuds like suspension is pushing on body which interferes with linkage. Does it happen with the body off?

I've seen this before, check your motor mount and mounting screws. While running the motor may be flexing in the mount binding servo linkage.

Try a stronger return spring or rubber band. Also check body rub.
