for a WD. Valve seals leak badly. Engine smokes on hillsides. Need to keep using tractor for a couple weeks. What mfg & part # would be less likely to foul?

Why is there never time to do it right the first time, but always time to go back and fix it?

Get the spark plug extenders, they have a small hole toward the piston, oil cannt get to the plug and foul it. I have a set in my toolbox for just such occasions. Got em at an auto parts store. Maybe the name was Nofoul. Your plug wont foul with em, power may be down and it will burn the oil now. HTH

Do what skip said use the nonfouler. I've seen them work on a wc that would spit oil on your shirt.

WD doesn't have valve seals. Just get the next hotter plug than what is recommended if you have oil fouling or do like Skip says.

Marion Klutzke of Lafayette, In. told me to use LM 49's, a mower plug, and they sure have worked for me!!!!
