I am having some issues with my new motor. It keeps breaking up on my after about 5000 RPM on long straights. It cuts out like it is starving for fuel. The motor has all the goodies on the inside. The carb is an EC dominator plus that doesnt even have 2 races on it. The motor runs great on short little tracks when you are not holding the throttle open for longer periods of time, but when I get on a long track i have issues. Here is a picture of my set-up.
I do not have that filter and fuel shut-off in the fuel line anymore.
Here is what I have tried:
-Tuned the carb about 5 different times and I keep geting the same result.
-Replaced the coil
-Replaced the spark plug
-Cleaned the magnets on the flywheel
-Checked the valve lash
-Tried 3 different fuel filters
-Replaced all the fuel line
-Tried a brand new fuel pump
I am thinking there is something wrong with the carb, but I am looking for other suggestions.
