Arc weld
Veteran Member
I took the front of Magneto off my SA200 and it was dry inside but I didn't see any points. If I recall, they put some kind of electronic parts in that replace the points?? The only thing with a spring was the guide that rode on the shaft. Slight bit of oil at the bottom but otherwise clean and dry. I sprayed a shot of WD40 in for good measure.
Then I took the distributor cap off and found the rotor inside. The contacts were black as well the rotor so I cleaned them with some fine sandpaper. Put it back together and it looked wet on the ground behind the air cleaner. Gas! I took the oil cup off the air cleaner and it was overflowing with gas. I thought it was supposed to drip from the carb but maybe it was a little gummed up from sitting. Dumped the gas out of the oil cup and left the cup off top see if it would fire. Fired right away! Couple more tries and she started right up with a big cloud of gray smoke out the exhaust for a few seconds. Smoke cleared and she was running great.
Left it run for probably 5 minutes and it never slowed down to idle. Then I played with the throttle and idler lever and it finally idled down. Put a rod in the stinger to set my heat and now the idler wouldn't speed up. Pinned it on high idle and it welded fine. Took the pin out and it wouldn't go back to idle. The R57 idler worked perfect before. I'm thinking of burning some bigger rods in it to see if the idler starts working again. Can sitting affect the idler? It used to idle down after about 25 seconds which was great and sped up fairly quick when you struck an arc. Your help would be very appreciated.
