Default Re: New Miss

Still sticks to my former advice, pull sparkwires to check if its a single wire/plug or a random miss.
You can force the rod on the carb to give it some choke while running it in high idle manually to see if its any difference.
Modern capacitors are often missing the springwasher in the bottom connecting capacitor internal to the can and goes open when heating up.
I have a 0.22uF regular axial capacitor on clipleads that can be attached to check if it improves from adding capacitance.
If it misses at random cylinders with leanest mix (cruise speed) can be from a lot of reasons, low spark wrong advance or just plain to lean mixture.
If you accelerate hard giving it richer mix will it improve ?
