Help: When I pull the pull starter, wheels of car move
I know this topic might not exactly pertain to this forum, but I feel I can get the best advice here, so that is why I am posting this thread.
I have a question regarding an irregularity with my car. It is an Ofna Monster Pirate with an XTM 24.7 Pro Engine.
Here is the problem. Whenever I pull the pull starter to start it, the wheels move forward. The clutch won't "freewheel". For a couple of pulls the engine piston will cycle without the wheels moving, but then all 4 wheels move forward simultaneously.
I am not sure what the problem is. I have owned other nitro cars before with both pull starts and starter boxes and I never had this problem.
The original engine that came with the car had a slighter shorter in length SG shaft than the XTM engine that is in there now. Even though the shaft was a little longer, the clutch assembly went together as easily as it went together with the stock engine.
I thought my clutch springs were too soft, so I changed to harder springs. The problem still persists. Maybe you guys can help me with this dilemma.
Any help/advice is greatly appreciated.
