The project actually turned out to be pretty easy and took about 4 hours to complete the grinding, phasing, and timing. I started by placing the "washer" on the distributor and rotating it to find the best location for it. I then took the washer with the module still on it, placed it in some vice grips, and started grinding down the washer, being careful not to catch the wires or module. I ground the washer until it just fit into the distributor. When you get to this point, you will find that the distributor base plate mounting screws and tabs will be in your way.

Now, install the "magnet sleeve" and distributor rotator on the central shaft as explained in the instructions. You will now need to "phase" the module so that it fires in the right spot. I placed the distributor cap back on the distributor and used a Sharpie to mark where the towers were on the side of the distributor, and then removed the cap. Following the phasing instructions use a test light to find out when the module "fires" when the test light goes out. You will need to rotate the module/washer until it "fires" when the rotator is directly over a tower, and thus sending a spark to the spark plug. You will need to rotate the module/washer CW for a CCW rotating distributor and CCW for a CW rotating one. Once you have located the proper firing point, use a Sharpie to mark on the washer where the tabs are blocking you from letting it sit on the distributor base plate. Take it over to the bench grinder an grind out the areas. I made mine a bit larger to compensate for errors of my hands moving while drawing the areas to grind out. You should have 3 ground out areas...notice how mine has 6...I had it off by about 1/4" the first time and had to do it again. Place the module/washer onto the base plate, set up the test light and spin the shaft to check the phasing again. If it is right, the light should go out when the rotator is directly over a mark you made of the towers location. Since the towers are set 90 degrees apart, you only need to check one.

Now, since your grinding most likely took out the mounting screw hole, you will need to drill and tap a new one into the washer and distributor base plate. I used a sharpie to color in one of the holes through the washer onto the base plate so that I could keep alignment. I then removed the washer, and base plate, and then drilled and tapped a hole to maintain precise alignment, and also provide the ground to the module. They were then both reinstalled into the distributor, and then the distributor back into the engine.

Some where in the process I messed up the timing, and when it was installed back into the engine it was pretty off. I hit the starter and a noticeable crack came out of the carb....oops, it’s firing on the intake strokes. (check out the article on timing the Waukesha FC) Once the timing was fixed, I hit the starter...just a quick tap...and it fired right up! Nice smooth idle, nice throttle response, and starts at very low RPMs. I am very pleased with the outcome of the modification, and the current performance. The engine runs very smooth, and so far has not given any hint of problems.

I hope the photos and text are pretty self explanatory, but if you do have any questions, please feel free to send me an email.
