I have a 1973 18HP model 18304A that I took apart for parts and now I am thinking about putting it back together and see if I can get it running. I did a compression test and have 100 on both cylinders, but I can not get any spark on either cylinder. I took the fly wheel off and re-gapped the points and everything looked really good up there. It had electric start and the harness to go with, but I took that off for another motor, so the little connectors that go to the kill switch are not connected to anything at the moment. If I remember, the kill switch is normally open and you "short" it to kill the engine, so not having them connected shouldn't effect spark...right? I feel like I am missing something simple. Could both coils be bad? I have never had this running...these are my preliminary checks before I decide to keep going or use it for parts. I have a mulitimeter, just not sure what to check and what readings I should get. I also have 2 known good coils in another motor, but I just got that one back together and really don't want to take that apart again.
