Finally got spark on all 4 but now its the worst motor I ever heard. I could barely get it to start and it kept killing and backfiring and would not stay running and made different pitch sounds. I think I may have crossed the orange wires from the ppack to coils on cylinders 1 and 3. I will check that. I was wondering if that could be my problem or if the flywheel key may be sheared? Now I got good spark, compression, and good fuel to all 4 carbs. But something is very wrong. Sounds like timing to me like sheared key or mixed up wires??? Does this sound right. I will take a look tmw at update. Thanks.
