I would try to shoot for the 7000 range on RPM. All the saw is doing is running the chain, far less load than a big prop will have. I think making your mufflers is the way to go and reverse engineering them is smart. Now if I only had a welder...
Do you have a torch. If you do you can go to a welding shop and get a wire for aumenam. You can weld it with that. It does work. When I get done with the one I am doing. I will put up how to pics
