Tip - I rotate plugs between the left and right cylinders frequently. Hotter NON resistor plugs, keeping the temperature over 180 degrees, and not running the carbs anymore richer then necesary can help reduce premature plug fouling which is a problem ESPECIALLY when using low energy Magneto ignitions. A tractor with an engine properly broken in and in good shape can be less sensitive to individual components. So when you use a resistor plug in plug as an element in a system designed for a non-resistor plug, you place an added unknown into the total circuit. You can go directly to Autolite and it will tell you that their 388 is a RESISTOR plug. I listed them from Hot to Colder. They have a longer insulator tip and they achieve a temperature higher than the deposition zone relatively fast. With the poorer quality coils today running more resistance on them can just shorten the life. Australia post usually allow upto 7 working days for regular parcels.

RFI, Radio Frequency Interference, the tac,tac,tac you hear on radio speakers around a non resistor type ignition source is what the resistor or RFI suppressor type spark plug was made to control. Almost every parcel local to Sydney will usually be dispatched via Toll. Try Brillmans or some of the other vendors or NAPA local if you can't find them. Zone of fouling with soft deposits- vehicle engine run at idling speed or its low load can result in the setting of soft (dry) combustion deposits on the insulator tip, even if the fuel does not burn in liquid state. Stay cool enough to avoid pre-ignition and/or electrode destruction due to detonation. Please try again later.
