Need Help Please ! HPI Nitro RS4
Hey, having a slight problem with my car. I had the car sitting for a while because I broke a gear on the 2spd trans. Well I finally went to pick up the new gear (after 7 months of letting it sit) and while I was at it I picked up a new 5.5mm 2 needle carb, HPI purple head and new clutch springs (the clutch shoes themselves are still good). After installing everything I decided to go out and fire it up. Well I got it all fired up and after about 5 seconds the wheels stopped turning (guess it need to richen up after sitting so long) and it was idiling normal then all of a sudden the car made this weird screech like sound and took off (without me touching anything) and then it stopped. Then as I let it idle a bit more and it did it again, when I hit the break the car stalled.
I tried to fire it up again and couldn't get it going again cause of a bad glow plug, but as I was trying to start it again I heard the sound again. If I pull the cord hard I can hear the noise and I can feel the car jerk forward. I can't for the life of me figure out what might be causing this. I triple checked the install of all the new parts and I'm starting to lose my mind.
Does anyone have any ideas? I would appreciate all comments and any ideas that anyone might have to help me get to the bottom of this.
Thanks !

I think AMG is talking about the needle bearing between the clutchbell and the crank shaft. Just grease it up and you should be good to go.

absolutely. i have a hpi nitro mini with a two speed in it that had the very same problem. change those stupid bushings inside the two speed to bearings and that will solve your problem. no question about it.
