I was keen to a do a compression test before I dismantle my Fulmar 15t engine to get a Guatemalan on how worn it is. Does anyone have any idea what level of compression is acceptable.

Remember that although it may have say a 60mm stroke until the piston covers the transfer and exhaust ports it can't compress.
