Subject: Pietenpol-List: "A" rebuild/MagnetosGreetings group,I've been enjoying the postings. Tons of great info. I have a question forthe model A guys. Are the modification plans in the 1932 Glider mag.complete, or are there some updated mods I should incorporate? Will I be okto follow those instructions word for word ?? I had thought of souping upbut now I want to keep it as simple as possible.That was Bernard's idea!Also, I have a source for 4 cyl magnetos made by slick. They are brand newin the box, 15 degree lag, right rotation. They were manufactured around1988 for ground power units. I have talked directly with Slick and theyconfirmed that these mags are the same quality as the aircraft version, justdifferent color. They come with timing instructions and hold down fittings.Somone tell me if I am missing somthing, but I think for $15.00 a piece,these will make a great ignition source. Email me if interested.Keep up the chatter. Chad.Chad, The mag installation on the model A as per the early magazine articlesused a mag with a reduction drive. It is direct drive at crankshaft speed.The Slick mags are intended to be driven from the engines accessory drivesat i/2 crank speed or camshaft speed. Great price though!You might be able to adapt them to the distributor drive out of the top ofthe head or from the end of the cam howevr that would change the rotation.The antique tractor guys are likely to have a crankspeed mag or know whereto get one. Know any of them in your area? As for the rest of the engine mods just follow the plans it works as is.John Mc________________________________________________________________________________
