Glad to hear such Dick and glad to be of help for that would (hanging a new engine) would have been a very expensive way to fix an ignition problem for sure

I would consider running either some of Yamaha's "Ring Free" product or (the very same stuff) some bottles of the clean up version Chevron's Techron product (should be able to find it at Wal mart for less cost in a black bottle) to help remove any left behind carbon deposits on the pistons from those cylinders running so far out of spec. If you think the plugs got dirty, they (the piston crowns and rings) are just as bad if not worse....

Smooth Running and Following Seas...
