Pinch question
Ok so here is my question, i race 1/10th turing cars and know about how much pinch my motors should have after a gallon or so. Im getting into 1/8th scale off road, but my .21 a novarossi P5X after a gallon feels like it has a lot less pinch that my .12's have in the past.
Thanks

An engine is not fully broke in until all noticable pinch is gone. If you are talking about compression that is a different thing. My P5X did'nt break in untill is hit the 1 1/2 gallon mark and now I can' t control the stupid thing!

regardless the pistons;sleeve fitting, if it's tight or loose..........
if your engine runs fast and has a consistent idle and if there's no play on conrod bushings, crankshaft pin and bearings............don't worry about pinch........
