I might be wrong I am just saying what I was told from my mechanic. I personaly have a Brison 3.2 and he's got this PE engine there. Since the engine had a crash in the water the cylinder broke, so he was looking for a new cylinder and he told me that he wasn't able to find one that would fit that engine. Now he knows that Sachs Dolmar Cylinders are used in all those engines, so I presumed that he knew well those cylinders. He stated that no one would fit the block. If you state that ANY one will do than I will thell him that.
I pesonaly have very little knowlege on Gas engines.
