well after weeks of being dumbfounded i finally got somewhere today, ive had a problem where the 2/3 cylinders would not fire at all for a day or so at a time and then start again. well ive been thinking ignition, (ignitor, timing pickups, coils) all that stuff well i never even thought before to pull the plugs. when i did today i found the two bad cylinders are totally black, well clean up the plugs and pop them back in and problem gone. now my question is whats causing this, ive messed with my pilot screws a tad just trying to get it in tune maybe i went too far? what way should i go with them to cure the black plugs?
