Had the same problem with my 41a which turned out to be the mag cap was cracked. Ordered new cap rotor and condenser which I'm still waiting for, but I'm sure will solve the problem. The cap had been siliconed before and was in pretty rough shape once I looked it over more closely. Ran fine one day and nothing doing the next? By the way a new cap was supposed to cost me $135.00 here in western canada but only $26.98 if I ordered from the us. Even after exchange it still was a great deal so if your looking for parts try Roberts Carb repair. Good prices and I'm hoping good parts as well? Good luck!

JDMAN..
You have bad points or condencer or coil or cap or rotor or mag impelse or grounded points or low power to the coil or bad wires or bad sprak plugs. Check everything and it will work.

If it wont fire the plugs and is a magneto, it could be the points or condensor or a broken or weak trip spring or a cap and rotor problem or the points may be grounded out from like a shorted kill wire or switch. If its a battery/coil igntion, see if it has power to the coils high (non distributor) side (need that b 4 u can do anything) when the ignition is turned on, and if so, see if a test light on the coils low side (wire that goes to distributors points) goes on and off as the ignition is on and teh engine is turned over. Not knowing what all you have and not being there, I would suspect burned points or no hot wire to the coils high side first. Post bac and Im sure clooney or I can get u hot again.

JDMANHarvey, we will need more information to help you.
~Does it have a mag or distributor?
~If it has a distributor does it have power to the coil?
~If it has a mag what brand?
~If it has a distributor what brand, Delco or Wico?
~What happened? Did it quit running, has it run since you have had it? ~Was it worked on before not starting?
~How long has it been since it ran?
