Hi everyone, I would like to start a summer project where I build a two cylinder engine that is horizontally opposed and uses off the shelf components to help make the build easier. Things such as: Two 6hp 2 stroke chainsaw engine cylinders with their matching pistons and rods. A diaphragm carb and a reed block to go with it. Ball bearings for the crankshaft. I believe most everything else will need to be fabricated. The idea would be to buy a couple pieces of aluminum billet and machine out a simple crank case for the cylinders to be mounted to. The crankshaft would allow both pistons to be on the same cycle during operation so I can get some nice scavenge action in the case and hopefully get the carb to come alive and provide fuel/oil to the case and cylinders. My question is if there are already plans out there for this kind of engine? Something tells me that it would be unlikely that this has not been done before and plans are not in existence for it.
