Hi everyone.
I need some help fixing my nitro buggy.
It's a basic buggy with vx18 engine and 2 speed gearbox. It's my first nitro car so I'm new to the hobby but already hooked up.
I crashed it the other day. It went sideways and it hit the kerb. When it hit the kerb the engine moved a bit but enough for the gear mesh to separate from the central differential (gearbox). A silicone exhaust coupler also got damaged (slight crack on the side).
1) I repositioned the engine and managed to start the car, It runs but.... When on the ground and accelerating it makes a noise like if it had a turbo. I thought it could be the damaged exhaust coupler but I temporarily fixed it and it still makes that noise. Doesn't seem to be making it when I rev the engine with wheels off the ground. What should I check and try to fix to get rid of that sound?
2) The oil seems to be leaking from somewhere, can't locate it. But I think it might be a rear pull start plate. Also exhaust manifold gasket probably. But when I cleaned the engine yesterday and fired it up for a moment it looked like the pull start plate. What else do I need to check?
3) When I pull my buggy backwards it makes that spinning noise, which I can't remember if it was making before the crash 🙈
4) Also when the engine starts it revs up a bit like if I'm giving it some throttle but I'm not and it starts pulling and wants to drive away on it's own. That wasn't happening before the crash.
I'll be very grateful for any help.
