is there a spark plug for the ixk3 engine that is better than the other for this application. i was thinking autolite but im not sure of the plug number.  it has the bigger base on it.   thanks,  tim

Personally I would stay away from Champions as they are not what they once were. I've had them foul out just from a little carbon on the porcelain. When replaced with A-C, Autolites, or Motorcrafts the problem was solved.

i agree with Blake ,champion plugs are not the quality that they use to be .if you are gas fouling the plugs make sure your carb. and magneto are in good condition ,also if your engine has a place for a thermostat ,put one in it ,that will help.the higher heat range champion plugs are w-18 and w-20 if you want to cross them to another brand . i can't remember the autolite #,but i will try to find it.

the autolite # is   3076, i believe that if you cross w14,w18,or w20 you will get this part# since popularity determines production a lot of the different heat ranges have been dropped.
