Enough to Pull your Hair Out

You ever set out to do something and get frustrated at every turn? The M has been running great and the last time I used it was just a few weeks ago. Last week I went to hook up my planter and plant some summer corn. She would not start. She acted like no spark. It's been a while since I worked on the mag and decided it was time to check it. While I was putting everything back together, I noticed the loose gas cap and then remembered I had drained the gas to use in my mower. Gas ran into the sediment bowl when I turned it on but there wasn't enough to start it. Five gallons of fresh gas and it started. I hooked up the planter and since there wasn't enough daylight to plant anything I parked it back in the shed.
Monday I went to plant and she would not start. I knew the mag was good so I decided the carburetor was dirty from that little bit of bad gas. After an hour of cleaning and rebuilding she still would not start. Maybe there was still something wrong with the mag. It worked really well on the test bench. I took it off and went through it again. Found nothing wrong. Put it back on and tried again. She cranked about five revolutions and BANG!!!!! That's not right. Yet tried it again, BANG!!!!! Scared the beegeezers out of me. Decided the spark plugs could be at the end and hitting occasionally with the manifold full of fuel. Went to town for new ones. They didn't have the ones I wanted so I had to wait another day.
Yesterday I picked up four new D21s and put them in. Cranked five revolutions and BANG!!!!!! I knew something was really wrong and decided to start from scratch. Checked compression and read 130 psi across the lot. Concluded the only thing left was timing. I popped the hood off and the valve cover. I slowly cranked the engine by hand and watched the valve movement while listening for the impulse click. Sure enough the mag was out of time. I pulled out the mag, reinserted it correctly, retimed it, and it started. Went out and planted 18 rows of corn and then disked up the rest of the garden. Somehow the mag's impulse driver turned 180 degrees back when I reinserted it. I am always careful to turn the engine by hand until the #1 cylinder fires before I take the mag out. Then when I reinstall it I turn the mag until #1 clicks before I reinsert it. This way I know it is always in time. I then fine time it to the notches on the front pulley. Each time I remove the mag I go through this procedure but somehow I missed that slip backwards. Today I came home from work and cranked it again. She started and ran nicely. Charged up the battery and shut her down. Moral of the story, pay attention to the little things.
