Can anyone point me in the direction of some technical information about petter type water-cooled 1500rpm engines please (are there some rated at about 6hp?). I need to know things like:-
- Combustion chamber design
- Compression ratio
- piston material
- which models are the most durable?
- how does their durability compare with a Lister CS?
- do they come with electric start?
Much appreciated.
