Hello I am doing up a Dennis Premier MK1 (36") and getting some life into it but could anyone help me out with the contact settings and tappet clearances please? Its the side valve Dennis engine. Thanks, Ben

According to a scribble in an old notebook 

Points 15 thou

Inlet 4

Exh 6

but I'm not sure whether this applies to the Premier or the previous model.

Yes, that is correct

 

The Premier Mk1 engine must be the best and most well built for long life engine ever fitted to  a lawnmower.

(Even if the external finish is rough on them, you need a mirror to check the oil  and the carburetor cracks around the pinch bolt!)
