Two weeks ago, the motor ran fine all day. Last Saturday, it started fine, but when I went to head out on the lake, there was a serious lack of power and the motor didn't sound right.
Stopped, pulled the plugs and they were seriously in need of changing and one of them (#3) was downright a mess. I've never seen a plug fouled that badly.
So, docked the boat, drove to Cove and got three new plugs. Put them in, fired it up...same problem. So, we decided to fish it that way and stay close to shore.
Last night, I checked for spark in all three cylinders....it's there. When I pulled the new plug from #3, it was mess and looked like it was already 5 years old. There was a little oil/gas mixture that dribbled out of the cylinder. Obviously, it wasn't firing. I cleaned everything up, put in one of the cleaner old plugs and ran the motor. It seemed like it was firing once in a while. The #3 plug was warm, but not as warm as the other two.
I pulled it out, noticed no dribbling out of the cylinder, put in another old, unfouled plug and ran the motor. It definately ran better, but the #3 plug still didn't get as warm as the other two. It was a different brand and a buddy told me that different brand plugs will run at different temperatures.
I ran out and bought three new NGK plugs, gapped them and put them in. I am hoping that the motor will run now and I'll test that tomorrow night.
I have a theory that the #3 cylinder had so much dump in it that it just immediately fouled the new plug right after it was put in.
Any thoughts on this....similar experiences??
Tell me I don't have a bigger problem.

I really don't care about that.
Sad to say the best chance of a championship at the moment in this state is the Twolves.
Used to be such the fan, but the NBA lost me with the pick and roll.
But I'll watch come playoff time.
If KAT can't play worth a darn , the playoff run won't last long.
I thought I couldn’t dislike Glenn Taylor any more than I already did until today:
Glen Taylor with @ChadHartmanShow when asked if the reason for this happening is because the franchise might be worth double what he was selling it for:
"Partly so, yes. I have a responsibility to those who have been on this ride for the last 40 years."
Sellers remorse for sure but too bad for him the deal was inked 3 years ago. Hopefully the league has a way to arbitrate so it doesn’t go to court, but we will see.
