Here is my delima. I have a 1971 20hp chrystler that ran fine last year. When I went to start it this year nothing happened. I pulled the plugs and while pulling the the rip-cord didnt get any spark on either plug. Then I pulled the plugs out of the wires and held the spark plug wires while pulling the rip-cord and no shock. I had a guy tell me to replace the coils, but I have a problem believing both coils went bad at the same time. My question is can I check the coils without buying new wons are am I going about this wrong and should check something else first. Any help with this matter would be greatly appreciated.
