One exception to that, the lines may run up hill from the gascolator and then down to the carb. Any water/sdiment left in the...

All, Thanks for the replies and opinions. I spoke to Bill Middlebrook this morning from Penn Yan and he indicated that it is not that big a deal to place the plug,gear, and govenor housing at a later date if I decide to go CS in the future. The L2A model is one of the newer manufactured Lyc's used by the 172R-SP which are configured with two accesory (vaccum/haudraulic) pads on the accesory housing. Bill suggested to leave as is and if I...

Although I would like my plane to go as fast as possible, speed is not my main reason to cut the pipes. I was thinking that by cutting the pipes, I would of course reduce the weight, but there would also be less weight (and less length) to vibrate and damage the welding of the exhaust or the mufflers. One important thing to consider when cutting the exhaust short is that the floor will get hot(ter) Because the fuel lines are running in the...

I think you'll find it unanimous. Too close.

..... ..... Thumbs UP !

Hi All, Last fall, I posted a few pics of an IO-360A1B that I purchased that had 0 SMOH, but was pickled in 1980 in Colorado. Well, I was pretty certain, that since I was taking myself, my wife, my kids, etc in this airplane to be, the engine required a tear down. So...off to Aerosport power, for teardown, inspection, and reassembly. As a recap, here it is before: Here is the case inside: Corrosion was pretty much non-existant according to...

There are hollow shafts for constant speed, solid shaft for aerobatic aircraft(not constant speed compatable), flanges with and without lightening holes. There are supposedly thicker flanges for aerobatics. Otherwise, leaving out the H models, as far as I can determine, any crank will fit any case. I am going the same route as you, I have a junk crank with lightening holes and a good crank without and as far as I can determine they are both...
