One plug with too much fuel can give you a wrong impression of ign. breakdown-- adding a bit more timing and a minute or two at idle can clean up your miss to go win as happened to a fellow racer who ask for my help sat. night after fighting this three races on a new motor with added cooler lines in his intake! We read the oil on number 3 and 8 to see the difference in burn factors to find #8 too wet to fire properly all the time! The norm is --pop in exhaust is fire and back threw the intake is fuel related or valves, low timing can fall in on both as unburned fuel fowling the plugs!!! Plug gaped differently as valves too with solids can improve and balance out burn factors to get more horses out of your engine!!!

Rule of thumb! Back threw the intake poping--valve train and in the ign.fire if in the exhaust! We have had most all happen in 35 years! From a loose battery conection to a tach going bad! From too lean to too much fuel only on topend! A poor ground at the coil to broken valve spring! From restriced flow on one side of the carb to a leak in one header tube burning a wire! Just a few and you you have or have had an odd thing happen,please post it for others as some have been hard to find or figure out!!! Like too much fuel making a clynder run lean by buring in the header tube and sucking it dry or a vibrating ign. flip switch at high RPMs!!!
