I was hoping someone can help verify what is going on with my 1947 H. I've recently completed and overhaul of the engine. Upon initial startup in ran very well, nice and smooth, so I know it was timed properly and everything was working correctly. In the process of fixing a couple oil leaks I had to remove the magneto and re-install and re-time the engine. I've triple checked the timing so I think that is correct. The #1 and #4 are firing appropriately, but #2 and #3 are not. I swapped plugs #4 to #3 and #1 to #2 with the same result. #2 and #3 not firing. I swapped plugs back and swapped wires to verify its not a wire issue, had the same result,#2 and#3 not firing. I used an inline continuity tester and #1 and #4 the light was nice and bright, for #2 and #3, there was just a very weak light. My conclusion is there is something wrong with the magneto. Has anyone experienced this where the magneto doesn't fire just a couple of cylinders? I would think if it was going to fail, it would fail for all four. The magneto was rebuilt with the overhaul and has less than 10 hours of operation at this point. If it is in fact the magneto, is it possible it's an easy fix that I can do? Or will it need to be sent off for repair? Is there anything else I'm missing? Thanks for any help.
