Default Revo 3.3 issues....



I am new to the RC world and recently purchased a Revo 3.3. I had it out the other day and was bashing with some friends, took a jump and fell from about 6 ft up onto dirt right on the engine. It stalled and when I started it, it revved out of control. I pulled the engine to discover a broken engine mount which Ireplaced. The over revving problem is still continuing. Anyone have any idea what this could be? Tranny issue?

is it reving un-controlled? As in your not on the throttle?

Check the crank case for cracks.. You probably cracked it which means air is leaking in and leaning your engine out

It is revving uncontrolled...and I did check the crank case and didn't see any cracks. Spur gear seems fine. I might yank it apart again and seal the carb.

Carb slide valve? I reset the factory settings. I assume the valve slide is what the idle screw ontrols. This is at the factory gap.
