Rough Running.... Need Help

[hightower]

Ok, so going to skip the float bowls for now and worry about the spark connections. I like things mapped out so I know what I'm doing, so how does this sound:

1) Clear drain holes and make sure water can trickle out (before removing plugs)
2) Give plug entry point blast of compressed air before removing plugs to blow away dirt
3) Remove plug caps (after labelling if not already)
4) Remove plugs, label up, and store in house overnight to dry out - obviously give plugs a once over and check gap here too
5) Refit plugs
6) Refit caps making sure the connection/seal is good
7) Give the open part of the plugs and leads a spray with WD40, and then refit the rubber boot
8) Try it out

Have I missed anything off, done something in the wrong order, or put in something that has no place here?

Thanks
