Hey thanks for the replies. I just came up from double checking the measurements. The stroke is close enough and given my crude measurements .030 I will call it even. The pistons are both Labeled Guzzi ACA. Both sides had base gaskets .020 thick. It was running fine when put up about 5 years ago. I am in the process of recommissioning it. I could see some weepage on the right side in the head gasket area. I ordered a gasket set and it should be here tomorrow. After noticing the different piston heights at TDC I decided to pull off the jugs imagining the worst. I noticed that the left piston is .020 from case to piston at BDC. On the right it's .050 and winds up lower than the left at TDC. The barrels measure the same every where. It does not make sense. I guess my plan is to put the left side together as normal. Then dry assemble the right and see where I am at. One more clue is the left side was burning nice. The right side is looking rich. This could mean be caused by a few things, possibly lower compression? I should be able to get better measurements with the barrels on. I will keep you informed when I have proved myself a fool.
