Hello,

I have a hyper 7 with a .21 picco and when i use the Good ofna starter box the engine races at full blast and won't go to idle. What engine and/or carburator adjustments should i make?
I am a beginner and it is a used buggy.


Thanks so much

take off the air filter and look inside the carb there should be a very small opening if there isnt then you need to remove your servo horn and see if you can move it down, if you cant then its the idle set screw and you'll need to turn it out until the car will idle without engaging the clutch. If you dont understand then turn on your radio with the air filter off(and the engine dead) and hit the throttle, then you'll see how it works.
