I stopped by my local independent autoparts store today to get a new set of plugs for the 310 dozer.It had 2 AC-C86s and two Champion D16s in it when I tor it apart.
He asked what was in it, and I told him. Also told him that I didn't want new champions, as everyone condems them. He asked about the condition of the plugs which I told him had deposits on them. He asked if the deposits were black carbon, and I said yes, and continued to tell him that the rings were shot, and now I have all new pistons and sleeves, plus a completly rebuilt head with all new seats, valves, rotors, and guides. He is not your typical auto parts guy. He asked if the engine was a 148, without going to any books or computer. Probably now you guys are thinking "wow", but He has a really nice original VAC14 with M10 mower, and a nice original 311B with a 291B loader. (A Case Guy)
Getting back to sparkplugs, he told me that Champion now recomends D21 plugs which fire much hotter. The reason being that when D16s were recomended, we had leaded gas and the lead deposits on the plugs made them run much hotter. Today the plugs have a higher resistance to make them fire on no-lead gas, and required the ignition system to be in top condition, to fire them. He said that Champions were just as good as any other brand on the market, as long as you used the proper heat range plug, compared to other brands, in the same heat range. (Apples to Apples comparison). He said way too many people go to TSC and other places and buy what their outdated manual said was recomended.
Anyway what he told me made sense to me, but he did sell me a 4pack of 386 Autolite plugs, that were less than 8 bucks includeing tax.
