You should be able to get away with a gap of .028-30... No need to go that close IMO, but if you have problems go down from there (25...22)
Also You might want to look into the rubber boots from your COP's... there might be a rip/break somewhere... pull them all out take them off u'r COP and inspect/replace as needed.
btw, I've replied to u'r PM as well.

What gap should I use? around 0.021?
Another question, lately I've been getting starting issues. Doesn't start cleanly or requires a few tries. Meaning it cranks, but does not start. The issue usually arises when the weather is rainy, probably due to excess moisture in the air. Can the current plugs be inspected, cleaned out and put back (I don't think they are that old); or is it better just to replace the plugs.
If it is a moisture issue, what's the best way to prevent moisture affecting the plugs in the future or to correct current problem with old plugs.
