I have a stock 3.3 and for a while now its not wanted to pull wheelies. Today I noticed a binding feeling between spur/pinion but upon closer inspection it seems to be the clutch bell/pinion that is a bit stiff. Ez start works, not great as I think the motors on its last legs but it does eventually start. It didn't appear to be this bad last time I used it.
Does anyone have any suggestions as to what it could be? I'm not that familiar with dismantling nitro engines but I'll give it a go.
Any help is appreciated. Thanks guys
