ms261 problem. back firing

[spudulike]

Just had a MS261 in for this exact fault, a big backfire on trying to start.......the flywheel removed and the key is obviously sheared off. The clutch on it was brand new and the flywheel was sporting a big gouge so reckon it was jammed in place and the clutch removed which spun the flywheel.

 

The only addition is that the key is a moulded one on the MS261 flywheel so a new flywheel is ideally fitted rather than a new steel key fitted!
