muffler for os 40la
The O.S. la engine series in my opinion are the best engines for a beginner. But if you want more performance get a O.S. fx, while your at it spend the five extra dollars and get a .46 fx. They are the greatest .40 sized engines on the shelf. As for trying to beef up a la I have never really tried to put the effort into a engine with bushings. But I guess anything is possible. But really if money allows get a fx.
