Thanks Jeff they had to use the spacer on the PT bases, but on the newer bases they don't need to because they are designed for Briggs motors only, the base is 20mm higher in the middle compared to a PT base to lift the motor up. I haven't checked the ally ring to see if a PT will fit. I can post you one if it does.
