Ok so I think I have a problem with my Revo 3.3 TRX Engine.
I set the truck up on a stand and with everything set back to factory positions. However no matter what I tried I could barely get the engine to idle without cutting out, or the engine suddenly revving up.
More or less I feel this is pointing to an air leak somewhere causing the engine to unnaturally lean off.
A bit more investigative work needed I think, hopefully it won't involve removing the engine completely.
Here’s hoping for a quick fix, i really want to get stuck in with using this truck!
