Default Newbie motor question

Hey guys,

I have gone to a different brand and % nitro fuel for my Mad Force.

On its first run with the new fuel today it wanted to stall (and did stall) when I put the breaks on.

Does that mean I need to atler my throttle idle? Or am I way off the mark?

Thanks!

Steven

you need to retune the motor for the different % of nitro fuel.

well from what i have experienced wit nitro % changes is that the higher u go, the higher u have 2 have the idle screw....so increase the idle screw 1/4 turn at a time til it idles under all conditions.....then if its 2 high and the clutch grabs, lower it really really slowly til it doesnt move.

problem solved!

When I say different percent it went from 15% to 16%, so that shouldn't make a whole lot of difference should it?

No, it shouldn't make too much of a difference. But the fuels might have a different percent of oil in them and this may be what is causing the problem. The higher oil percentage the cooler the engine should run. The lower the oil percentage the hotter the engine will run.
