Hi all

My friend has a similar problem, new unit ran in, it will run arround quite happily on 1/4 throttle but as soon as you try to go over (even with slight movement) it seems as if the engine struggles then dies, this does not happen when the car is on a bench rest, it will attain full throttle under the load of the wheels spinning in free air only, and with a slight hesitation at 1/4 throttle,
all i know about the car is its new, 1/10 , rotary carb,
Hope someone can help
cheers

AL
