RE: 3.3 idle problem need quick responses
Pull off air filter and adjust idle screw until you see a 1mm gap ..make sure your transmitter setting isn't keeping it idle..that gap your putting in allows enough air in to mix with fuel to keep it running when you let off throttle ...after you have it running the idle may need more adjusting to idle up or down more..the 1mm is a starting point..that should fix it..make sure to put air filter back on before even trying to start it
Hope this helps
