My Mountfield Emperor Briggs and Stratton 4HP won't drive... ?
Blade goes round - cuts well - but roller won't engage to drive it forward - I've checked drive belt and it seems ok. Clutch not engaging or could be something to do with the roller? Any ideas please??
The pulley on the auxilliary drive shaft coming out of the engine, will spin on the shaft unless keyed or pinned to the shaft with a roll pin( which can shear) . cost of new roll pin £3.08.
