You have to use points with that coil.Or buy a magnetron conversion if you can find one.
Jacks Small Engines has a Solid State Coil #440417 that fits you motor for $ 39.15

Barry 1:
Thank you so heartedly for your information. I ordered what you recommended above yesterday and await its arrival. I will let you know immediately how it works out. I am repeatedly reminded how user friendly this forum has been to me in the past as well as the present. I am a retired surgeon and garden a 1.5 to 2 acre garden and all the produce goes to church kitchens, food banks and neighbors. I used to use a walk behind rototiller to control grass/weeds but since turning 80+ I have slowed down and I really need the Sears tiller attached to a nice Sears Suburban 15 I got a few years back. I also have a Cub Cadet 124 with its model 1 tiller attached but wasted a lot of time trying to convert to its creeper gear but it kept slipping out. Most all of the work is used to cultivate grass and weeds between the crop rows, other than corn.
Thanks Again

Barry 1: I got the coil you recommended from E-bay and installed it today. Sadly, I get the spark on the test light but do not get the spark on the plug. I reved up the flywheel with a drill but not difference. I very carefully set the gap with a business card, index card, metal gap setters both at .010 as well as .020. I made sure that the kill spark tab is not in contact with anything and the coil is oriented to the outside as directed. I also tried different new plugs and set their gap as close as possible to .025 but no spark jumping the gap. At present my question is: could the magnet on the flywheel be too weak or worn. I also note that when I set the gap over the magnet part of the flywheel, when I hand rotate the wheel, it seems that the coil columns almost come into contact with the non magnet part of the flywheel. Do flywheels deform or warp?? Talking to several shade tree mechanic buddies of mine, that have never encountered a "bad" magnet. I will rummage in the junk pile for a B&S flywheel of similar design and give it a try.
Any other suggestions other than the Harbor F. Preditor replacement .I have a small Honda ?6 hp, would it be worth a try?

Thanks Again

Gentlemen: Finally the answer to my dilemma...As I set the coil over and over again using business card, index card, .010, and .020 as I would manually turn the flywheel, it seemed to "wobble". The shaft that the flywheel attaches to is slightly tapered and a few steps back I noted that the key way pin was horizontally sheared and I obviously had to replace it. 3/16 I believe. I noted some difficulty when the flywheel was pressed back onto the tapered shaft. The key way seemed to climb up the taper of the shaft. With all this I really took the time to hammer the flywheel onto the shaft and I seemed to improve the balance and there did not seem to be any wobble. Putting all the components back together and using an index card to set the gap between the coil and the magnet...bam...I finally got spark to the spark plug and the engine immediately started after wards. What a learning experience and again I wish to thank those who offered advice. Tractor by net has been a very helpful forum to a rank amateur like me.
