I have an 87 Cougar that has been in and out of running the last 3 years. New pistons, rings, seals, gaskets, cdi box, coil, plugs, jets, and carbs. Brand new components on this 500 fan cooled spirit motor. I am not getting consistent, if any, spark right now. Last year's compression was 90 psi and needs around 110. Any idea on what action to take? Motor won't pop, very frustrating considering the new parts all over. Thanks for the help!
