There are many companies making conversions for leaf blower motors and weedwacker engines, or you could take it to a machine shop and ask them to make a prop adapter for you and modify it for you. mounting them is sometimes tough, standoffs are usually hand fabricated to mount them.
yeah i was going to end up forging my own mount i see no other way to do it. there is a plate in the back i am going to take off and cast a new one in plaster-of-paris with a engine mount included. and then poor in a metal. will either use aluminum or nickle. as you all can tell i am still in the planing phase, but i appreciate all the help as i start to build i will post pictures in here
Hang on a minute with your casting plans. Plaster of paris is not a suitable bold compound. It is just plane dangerious. Plaster of Paris will break down at a high temp. You have to have the mold hot, at least 300 degrees or more to drive off the moisture in the mold before pouring molten metal into it. Even if you are pouring into a metal mold, it has to be hot. I got in a but of a hurry one day when pouring a billet of gold. THe billet mold is steel. I didn't get it warm enough and when I poured the molden gold in, the steam blew it right back out. Nothing like having a 1/4 oz of melted gold spraying out like a gyser. That was with a steel mold and only the moisture in the air. If you try that with plaster of paris, all the moisture in the plaster will instantly turn to steam and blow.
One other point, if you have the ability to cast and then machine a new case, why not must machine one from a billet? In any case, you final cost and the reliability of the engine, and the overall weight will be much better with a comercial engine as suggested before.
