I run champion, They are the only plug the stores near me stock. They seem to work just as good as the bosch that came in the saw stock. Since Im the only running them on this thread I have to ask , Is there any known problem with champion plugs?

Ive head of them, (Champion) coming apart in an older post and trashing some motos,,,, I think The BOSH WSR6F and the NGK BPMR7A Plugs without question last the longest in that order..... and performance wise (Power) it is a toss up,, I tend to 25-30 saws between 4 contractors on a regular basis and when it too wet to work I help out @ the stihl dealer if they need me and it is the same way we put bosh in em un less they ask for NGK....:chainsaw: :chainsaw: :chainsaw:
 
NGK iridium and Ford plugs

Does NGK make an iridium plug for saws? My quad came stock with NGK iridium and I Haven't had a problem with them and I have abused the wee out of the thing.

The only plug problems I have had were with champions in a ford truck. I have heard that fords and champions don't mix but I duno weather that is true or not.

NGK has the new iridium plugs, but I cannot find one for the size that Stihl takes.

Also you are better off with Autolites in your Ford engines. All my Fords ran better with them (Champs sucked). My '55 F100, '67 Mustang, and Galaxy 500 all ran better with Autolites. I do not run them in my Ford F250 'cause its a diesel.
 
I tuned motorcycles a couple years a quarter century ago. Back then NGK always seemed to last longer then Champion.Nipendenso did significantly better then Champion but not as well as NGK. In saws I usually use Bosch and once in a while I use whatever is easyto buy. I haven't been having plug problems either and use 25 to 1 mix exclusively.I do maintain the air filter regularly each day and adjust the carb to my mix. I run mostly well used saws most often and use most any air cooled 2 stroke oil. I have a freind who bought an echo 660evl new and has been using rotella 15w 40 for saw mix since it was new with no plug fouling problems.
 
My grandpa told me never to buy a Dodge because the manufacturer thought they were only worth putting champion plugs in.

NGK or bosch in the saws.

Autolites in the cars...Those things will fire in mud! seriously.... blew a head gasket once and had to limp it home almost 80 miles from the track. Damn plug still fired when the motor was toast....lol.

Wanna make a parts guy cringe? Go to the parts store and order a set of Autolites for a Chevy, he will argue with you for hours, but they make them, and every Chevy I ever owned loved them!

Excerpt from NGK website,

"Spark plugs are the "window" into the engine , and can be used as a valuable diagnostic tool. Like a patient's thermometer, the spark plug displays symptoms and conditions of the engine. The experienced tuner can analyze these symptoms to track down the root cause of many problems, or determine air/fuel ratios."

Not only that,,, while the plug is out and I am reading the electrodes color,,,, I like to also use a bore light especially on a fresh rebuild to also read the top of the piston for my flame propogation pattern/color or even to look @ the ports and especially one thats been ported to check the plating @ the transition for signs of wear/anomaly,,,

Good post DGG,,,,,,, for a :newbie:
 
The bore light is a good idea. I'm going to try that next time I have the plug out.
