What is a "Rule Of Thumbs On Spark Plug Gaps In Small Engines"? Or! Please share links to good charts related to various brand plugs and gaps in basic small engines. Otherwise, would you agree that .030 is the basic gap and largest? Would .020 or .025 be the smallest gap used? Would a smaller gap only reduce the life of a plug or create more heat and cause misfire problems?
My recent experience was to a Champion RJ19LM in my 6 HP Briggs Mower bad after about 5 yrs. It has always started 1st or 2nd pull and continued with the new plug. The new plug appeared to be factory set at .025 and is where I left it. I have not used it to ck performance vs just starting.
