I have a 40 hp mud buddy with 25 hours on it and I'm on my third set of spark plugs. I was wounding if anyone has problems with there MB fowling the plugs. Alittle info the motor has dual exhaust and the governor has been ajusted prior to me purchasing it not sure when that was done. The dealer that I bought the motor form hasn't been real helpful with my problem. After the first set of plugs fowled I went up to a hotter spark thinking it would help but it hasn't. Any inputs would be helpful.

Might be running to rich . Just a suggestion and i had that prob with champion and i switched to NGK and havent had a problem but i also adjusted my Lean to rich on my stock carb

yours may be different !

Thanks for the suggestion I picked up a different brand of plugs today hoping that would help. I was told that champion was having problems with some of their plugs.

Not sure but i run NGK in everything now...... My honda wheeler and mudmotor run on same spark plugs so i just bought a case of them.

Where's Coe to tell him this is a B&S issue and not mudbuddy?

If you want to get all technical it's actually a 40 kohler there dic...
