    Well for the .45 to .60 size small case engines. Jett actually makes one pipe tuned for higher RPMS. But their Evolution engine tuned pipe is setup for lower RPMs though to match the Evo engines...

    Davis of Davis Diesel Development did put in his instructions (with some of the heads at least), to break in the engine using glow fuel first before switching it over to diesel. At the time I assumed...

    Yes the little Novell 1/2a engines tend to work well with 20% nitro glow fuel. They can turn some good RPMs too.

    Actually it isn't the rod on the Cox .049 engines. It was the crankshaft breaking. They do make a stronger crankshaft for the Cox engines to run them as a diesel.

    There is a fellow in the UK that makes piston rings for model engines. So we now have a new source for piston rings. We can get bearings from several sources so that should not be a problem. Other...

    Actually with muffler pressure, you may see a little oozing of fuel around the threads on the MK-X types of two needle carburetors. So since the fuel is oozing out, then it cannot be an air leak. ...

    It also depends on the type of four stroke engine to compare too. Plus the type of two stroke engine too. Some two strokes develop quite a bit more power than others did. The first and earliest four...

    A 20x6 prop is within the range of props for the Super Tigre 2300. So it would not hurt to try it. The Cub should fly fine with it too. At full throttle you can expect about 1/5 ounces a minute fuel...
