RE: Traxxas 3.3 hard starting issue and idle issue
I seal all my motors right off the bat. Even new they can have slight air leaks that can make tuning a problem once the engine starts to age. To start mine I cover the exhaust and spin the motor over with the cheezy start till fuel reaches carb. I then use a glow igniter instead of the cheezy start glow wire. My trucks fire right up everytime. It seems the EZ-Start just doesn't put out quite enough voltage to the glow plug for me.
