Spark plugs

I am going to swap out my champion plugs for my D14, everyone says to go with either AC Delco or Autolites. I can't get the autolites locally and when I do find them they are really expensive. I have been told the AC Delco R45's are the ones to use. When I went to go check them at the store there was no straight R45's they had R45TS, R45TSX and a different one maybe R45TSX-L? Anyways which one should I use? Thanks

Around here at the parts stores and napa the Autolites are about $6-$7 each and that's if they are available at the warehouse. A lot of places don't carry them anymore around here.

I just bought a set of autolite 295 for my D14, they were $6.00 for 4, which I didn't think was too bad. How much do you pay for plugs?

You have to go to a real auto parts store, and have them order them for you.

The R45TS is a TAPPERED SEAT EXTENDED TIP plug. The R45TSX is the same plug but made for a wider(.060") gap. I do not know what the -L is but your engine DOES NOT use tappered seat plugs. If it were mine I would use R-19LM Champion (OMG) plugs. I have NOT problems with them in small engines and they are the same heat range as the old AC 45's and the J-8 (OMG) Champions. To the Champion haters out there, I would like to see a head to head compairison of PTO dyno HP of Champion and other plugs gapped at the same gaps. I dought you would see ANY differance. Kent

Today's Featured Article - Bad Vibes - by Curtis Von Fange. One of the strangest ways to communicate with our tractor is to ask it how it feels. "Ask it how it feels," you say? Yup, ask it how it feels. Now, as with the other articles in this series one has to be able to hear what 'ole blue' is trying to say in response. The nice thing about our old iron friends is that they are usually quite consistent in their response, rather unlike some people I know who might change what they say due to the weather or other mitigating circumstances. But since t ... [Read Article]
