Fitting my red Kirby 4 stroke engine to my restored SB33 0919 (flat bar handles).
I find that the engine output shaft contacts (end to end) to the clutch shaft inside the friction clutch housing. This stops the engine sliding over the engine securing bolt holes (4) on the solid base plate by approx 10mm.
Any ideas why this is happening and what solutions are out there. The clutch lever is not engaged, I could shorten up the engine output shaft if the problem is caused by mix matched parts.
(I have sourced parts from two SB33 wrecks, so the restoration is a mix match of parts.)
