I always thought splitfire or other multi electrode plugs were just another gimick to take your money and work no better than a conventional plug, well my opinion changet a couple years ago. I have a cheap Ryobi string trimmer and leaf blower from TSC that tended to foul plugs. The carbs have no high speed mixture adjustment and tend to run rich at our altitude. I really did not want to lean out the oil mix any, yet was getting very few hours out of a plug, especially at light load. I tried different brands of conventional plugs with no improvement of the fouling problem. I was back at TSC for about the 4th set of plugs when I noticed the E3 sparkplug display in the lawn/garden section. The bubble pack said more power and use less fuel, I thought "yeah right", then I noticed it said " guarnteed not to foul or your money back" I thought "oh really ?" I asked the counter man, "will you honor this no foul or money back warrenty ?" He said they would. OK, I bought a magic E3 plug for the worst plug fouler, the string trimmer. I ran it for the next couple weeks and was not able to foul that plug even when I purposly idled it too much.
I then put them in the Ryobi leaf blower and the 2 cycle Lawnboy push mower. The mower did start easier and leaf blower did not foul the plug.
OK, this is good, next lawn garden machine project is the 20 year old Roper rider mower with 17 hp Briggs twin. This Briggs engine has been a hard starter as long as I have owned it (6 years). It would not start with the throttle at any position but slow idle, and would miss under a hard pull. I thought weak ignition, so I replaced the coil /module assy. Waste of money , It improved nothing. several sets of conventional plugs of different brands were no help. OK lets try some magic E3 plugs with the goofy bottom electrode. Tried them, and now it fires right up cold at even wide open throttle and does not miss even under a full load.
I got my education that not all this stuff is snake oil.

Today's Featured Article - Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
