Please send it to me off-list or if it's on a webpage, send me the URL. I'm trying to get an idea of geometry and general physical arrangement. Thanks!

I think Steve has a point in this posting. I have heard about it for long time. The reason could be that the carb heat, making the air go though all that places, makes it dificult and doing some suck of the gasoline in the carb, similar as a butterfly choke acts, orf the hand over the old grass cutter engine, this to get more gasoline in the system, Some pilots use it in cold weather when they think that too much primer could flood the engine with crude gasoline. Using the carb heat will finally make a little richer than normal air/gasoline mist go inside the ignition camera, helping the correct fire and for this reason the start of the engine. At least this is the way I have undertood it. I could be wrong.

All it does is pull unfiltered air by the exhaust manifold to warm it before sending it to the in carb. All it will do till the engine is running is allow for something to get pulled into places you don't want it. Things like ice, slush ect can make for an annoying if not expensive day. When an engine doesn't start properly, there is a reason. Just because it will sooner or later go doesn't mean the problem is not there and rarely if ever do airplane parts wind up on a clearance sale. Might as well find and fix the problem. I suspected it might be the impluse coupler and the previous post confirmed it. That should fix the problem. Just be glad you only got tired arms to find. it. I know of one case where a company renting a 152 had the same problem with the same symptoms. They just kept cranking on it until they had to fix not only the impluse coupler which is expensive enough, but also had to replace the $500 starter to go with it. When an airplane does not work like it should, its trying to tell you something. Those that are wise listen. Mark ---------------------------------
