A very throaty sound
The first Lawn Patrol I have heard and seen running.

Quote
I have done my homework and rings and piston are the same as JAP Model 80 also being 46mm.
Paul, I just realised the significance of this. blush
The first Lawn Patrols were fitted with a JAP 80 engine -
so Boundy had an easy template for bits on his own engine.
Sorry for not catching-on to your point.

Cheers
