My friend has a US Sports inferno or MP7.5 i think they are called. It has a GXR .28. He started using 15% fuel and it goes like a rocket but the engine is getting very hot. What should he do as far as tuning etc to get the temps down.

Cheers,

Ben.

i found the user manual instruction for setting the low speed idling is alright, but the highspeed needle need to be at much richer than what they indicated on the manual. Maybe that would solve your heat issues. Im running 25% on the GXR.

tell him to turn the high end needle counter clockwise about 3 hours and try it again, if its still to hot go 3 more hours untill the temps come down, then fine ture from there....

by hours do you mean revolutions?
