    Which piston is it? Did you pressure test it?

    Pressure test the engine after you put it back together. What caused the problem the first time you rebuilt it?

    gpr's are notorious for the 3rd cyl running leaner than the other 2 but it is agood practice to pressure test the motor while you have it out. plenty of threads on here about how to do it. also check out the how to threads on carb tuning. good luck
