Hello Everyone, When I started writing this newsletter I discovered that I never uploaded the last Newsletter so alot SIMAR maintenance advise is now online. I recently acquired a Type 21C Serial No. 788. This is a late model SIMAR with Scintilla MV-Z9 flywheel ignition system. Scintilla S.A. of Soleure Suisse (Switzerland) also made the external mounted magneto used on some machines. After fixing numerous fuel leaks and disassembling and cleaning the carburetor, the spark plug would no longer fire. I have no material on this flywheel ignition system. By trail and error I came up with the following instructions. Remember the hardware is metric so don't loose them. Step 1 - Remove the screen by removing the four bolts. Step 2 - Remove the two screws and remove the plate that expose the two slots that access to the points are gain through. I removed the starting pulley for clearer pictures. Step 3 - The points contacts are located on the left and are set at .012 or at least the magnetos are. The lobe that open the points contacts is located on the flywheel.

Step 4 - Timing mark (red dots in picture) on engine housing is bolt hole under the arrow. The matching mark on the flywheel is the fin with the inside edge of the fin notched out. Step 4 - The points are held in place with two screws. There is no pivot point like most points. These screws can be reached through the slots in the flywheel. Step 5 - To show you what the coil and points assembly looks like I removed the flywheel. There are three sloted holes on the back plate that allow the timing to be adjusted, and secured with the three bolts. The flywheel will have to be removed to loosen and tightening these bolts. After I put it all back together a couple of pulls and the old girl came back to life. In fact it wouldn't stop, the throttle lever was fully closed and the cable adjuster no. 5278 was screwed all the way in. I had to short out the spark plug to shut it off. The throttle valve no. 8813B would not fully seat in the carburetor body shutting off the fuel-air mixture. The next item to investigate is the throttle cable travel, why aren't I getting enough slack to fully close the throttle valve. Next time on the Newsletter, same time same channel.
