I've got some preliminary numbers on the Kioritz versus Homey question. I've just completed the Kioritz 23.6cc engine with the 25cc crank that Keith from BME described. My Homelite with the prop hub, (homemade), muffler, carb, and Hall effect switch bracketry weighs 3 lbs. 1 ounce. My Kioritz weighs 2 lbs. 9 ounces with the same equipment. One half pound lighter! My Homey will turn a 16 x 8 APC prop at 8500 rpms, and according to Keith, this Kioritz ought to turn the same prop at 9400!! I should be able to get it mounted to the test stand and run later this week, so we will soon find out for sure.

I have been making mufflers by gutting and cutting down the stock steel mufflers, welding in a flat plate where I cut them off, and brazing in 7/16" I.D. brass tubes. They weigh around 6 to 8 ounces, (with the mounting screws). Does anyone know about what the various aluminum ones that are available weigh?? I'm thinking there probably isn't that much difference, as the aluminum is thicker than the steel.

Too much fun this hobby!

Take care,
