Ok I'm brand new to gas, just got my Rampage mt last week so forgive me if this a really obvious fix that I'm missing. While breaking in the engine I noticed that when I hit the throttle wheels don't move. The servo is opening and closing, engine is reving, but drivetrain does nothing. When I move wheels by hand all gears and drivetrain move like they should. Only thing I can think of is that the clutch isn't working. Anybody have any ideas, I would be very appreciative as I can't wait to get this beast dirty! Thanks.
