Any retail parts guys in here?

I need a favor. My local parts guys are stu,ped when I tell them I want a non-resistored plug. Can anyone help?
I need a plug that is the equivelant of the A/c Delco 43.

It's a 14mm thread, 13/16" socket with a 3/8" reach electrode. I found out that may be part of our ignition problem on the Fly.....can't run resistored plugs with a magneto.

Thanks

are you running solid core wire too? www.ngkspark.com.au

 

Autolite #75 or #85 (depending on what heat range you are looking for).

 

yep.

 

Go back to the parts store and ask them for their spark plug books. Every company will have a cross-reference chart in their catalogs.

...I can hear it now...
"I need a resistor plug for my car."

"What year and make is the car?"

"Its a ______ running a ________ with a mag."

"?" (insert stupid confused look here...)

(would be funnier if I knew what car you had...)

 

I think HotRodJosh is running resistor plugs & a mag. What's gonna happen that we don't know about?

Not really sure what it will do but...I read it somewhere that you never runa resistored plug with a mag.

Here it is off of Don Zig's magneto page.


If you have never used a magneto before; READ THIS
Magneto Users Biggest Mistakes...
Never do any of the following!


Never connect battery volts to a magneto.
Never use suppression wires or resistor spark plugs. Set the plug gaps at .018 - .020 for internal coil mags and .025 - .030 for external coil mags.
Never weld on the car with the magneto in the motor. The generating unit may be discharged.
Never rely totally on your timing light as your sole source for timing your motor. Timing lights are typically D.C. and magnetos generate A.C. They also emit E.M.I. (Electro Magnetic Interference). In general, timing lights with mags are one (1) degree late for every 1000 RPM of engine speed. For best results, use a timing buzzer. We sell them and you can see one at the bottom of our products page.
Never operate a magneto without all of the plug wires connected to the spark plugs.
Never run a cast magneto drive gear against a steel billet camshaft. If there is any doubt which gear to use, contact the cam grinder.
Never force a drive gear on the shaft when changing or installing the gear. It may change internal clearances in the mag.
On a single mag warm up with a duel mag drive system and Mallory mags; DO NOT disconnect the second mag from the transformer. Severe damage to the mag generator will occur if you do.

 

If Don says so it's gotta be true. Thanks, I'll print this for Josh.
