You can make a good jumper for a fouling plug by tying a piece of wire around the plus close to the top in one of the depressions in the insulator and then connecting the end of the wire to the spark plug wire. If the depression ring in the insulator is too far from the plugs top conductor just bend the wire close enough to the plugs top for the best gap and you are set to go for many hours of unfouled plug/s.

The first time I did this was about 1951 on my 1938 Ford Four door sedan. I also carried a five gallon bucket of used oil that I bought at the local station for .05 a gallon. Keep them wheels turning!

Heres the deal, the basic ignition coil just barely generates hot-enuff sparkies. Then when you use eather modern carbon-core anti-radiostatic suppressing sparkplug wire ...or... sparkplugs with a built-in radiostatic suppressing resistor, (8000 ohms is typical resistance) you will have used up allotta of your sparkie power and will start to miss because the electrons arn't strong enuff to jump the gap everytime.

You can semi-overcome this weak sparkie problem by narrowing the sparkplug gap to make it eazier to jump the gap; and narrowing the ignition points gap to make certain you are generating the hottest sparkie you can.

Howsomevers: bottom line on your old tractor, use good soft flexable copper-core sparkie wire and NON-resistor sparkplugs for besttest sparkie performance.

Also use HOTTER heatrange sparkies. Modern no-lead gasoline fouls sparkies with invisable contaminates that leak the lazy sparkies away before they have a chance to jump the gap and ignite the mixture. Also use HOTTER heatrange sparkie iff'n yer tractor is a worn oilburner, keeps from fouling the sparkies so fast.

As for your making the engine run better with an extra gap jumping from the sparkie wire to sparkie. This is a trick that works on aforementioned FOULED sparkplugs. (Infact you used to be able to by Champion's with a built-in air-gap inside the white insulation specifically for that purpose, jumping an oil burning engine fouled sparkplug, when you really need to rebuilt the engine to stop the oilburning) But I ain't gonnna go driving around holding sparkie wires so the engine will run smooth.

Since I don't have a Champ catalog handy, I'm gonna assume that your Champs D-21's are HOTTER than the D-16's. (which is what you want) BTW RD-16 is the resistor version of the D-16..... ...Dell, the self-appointed sparkie-meister

Ya know Dell, many years ago (Too many) I saw a gadget at the State Fair in Richmond, that was highly touted to save fuel, increase power, facilitate eazy-starting, etc. Usual crap of auto gadgets! Actually, it was a auxiliary spark-gap meant to be placed in line between the coil and distributor. Worked the same way as the idea about holding the wires off the plugs. He was selling many of them! Wish I had bought one now, because it would be valuable to sell on E-bay! ;-) Wonder what happened to the company that made it?? Probably bought up by the Big Oil Companies, hehehe! Lottsa fuel-saving gadgets never saw the light of day after being bought up by Big Oil! ;-) Still going on today. saw in the news that a Filipino Inventor had devised a neat gadget that purports to save over 30% of fuel, the Big Oil interests made offers, he decided to not accept them, plannning to market it in the PI. Hope he suceeds! Or Big Oil Will Send A Hit Man, hehehe!! ;-)
