An old friend gave me a 1970 SXLAO a couple years ago. It was stuck at the time but didn't take much to free up. It surprisingly has decent compression. It does not have spark however. I have a 1973 SXLAO parts saw that has spark. I would like to swap the whole ignition from one to the other. Is there a timing procedure or just bolt it on? Also, should I swap the flywheel also? Ron

You can swap them, on those older ones you have to remove flywheel to remove ignition you might as well swap flywheels

Ron,they're easy to swap once you have the flywheel off.There are 2 screws on the front of the stator plate on the points box & 1 on the rear by the coil.Once those 3 screws are out you can turn the stator plate while holding the plug wire & it'll unscrew.You might want to take the time to clean everything while apart.If there's a lot of crud on the fins you might want to remove the muffler to have easier access on that side.Yeah,it takes time,but better to be thorough now while apart.

Clean the sawdust soaked with oil off the flywheel and stator plate. The manufacturer should be stamped into them, front of flywheel, back of plate. Some were made by Wico, some by Phelon. The flywheel must be the same manufacturer as the rest or it won't work. Easier just to move the flywheel and stator plate together. Then you know it produces spark.
No adjustment for flywheel to coil gap. The point gap is critical. On my saws top dead center is when the keyway on the flywheel faces the center of the coil.
Blow as much crud out as possible while you have it apart. Especially blow out the cooling fins around the cylinder. If they're blocked the engine could overheat.
Remove the muffler and clean out the accumulated carbon. Make certain that none of the carbon gets into the cylinder. It could score up the piston and cylinder. The saw runs better if the exhaust is not constricted.
On mine the spark plug wire just pulls out of the coil, doesn't unscrew.
