Changed Plugs- now less RPM

[Mattash]

Hey Guy's,<br />I have the trusty Ol' 225 V6 "Looper" 1992 Johnson. Based on JB/Dhadley/and Dunk's recommendation , I wanted to replace the plugs with the correct Champion plugs. I got a set of 6 QL77-JC4's and when I went to replace the old plugs , I noticed they were NGK-...something. I replaced them with the 77's and now my WOT went from 5500 down to 5300. Is this normal or should I put the old NGK's back in. Or maybe use the Champs and re-prop???<br />Thanks for any input.

RI JOE, Hi, A very interesting post,Myself, and I'am sure others would be very interested in what would happen if you would go back to the NGK's once more...Thanks.

Hmm. That is strange. Yes, let us know what you find out. I may switch my VRO's plugs to MGK equiv myself
