Any Evinrude experts out there?

[Capt. Bob]

Well I posted to the various Johnson/'rude Forums and got little response so I thought I'd dance with who brung me  

96 200 V6. I'm fouling the lower right side (#6 I think) plug. The other five are perfect. I re-built the carbs last year and they seem to be working ok.
I can tell I'm dragging a cylinder while underway (sound, rpm fuel consump.) and it now backfires through the exhaust when I run it on the muffs. This is followed by a cloud of white smoke.

I know, it could be several things. I can clean the plug, hold it against the block and crank. I see a strong spark. Put it all back together and it fouls the plug.

ANY suggestions are greatly appreciated and as usual,

Thanks in advance.
