Need some advice, just tore down my R5T TE to clean it and noticed that at TDC the piston seemed to hit a flat spot. This is without the head on. I can actually get the crank to hang up at that position. Anyone know what could cause this condition? I did notice there was some movement between the crank pin and the rod bearing. Motor has about 2.5 gallons on it and still has good compression.
Thanks in advance.
