Stay tuned.

The resistor is located where the clamp is , the clamp that holds the choke cable onto the shroud. The resistor is inside the screened spark plug lead . It's rare to find a chorehorse with the original screened ignition lead.

These sets go for around $100 to 200 here. Depending on condition, they are often incomplete and in rough shape.

I've noticed: even when they don't have much compression they will still run ok.

Electronics 101. The ammeter is a moving coil meter, able to be utilised as either a voltmeter or a ammeter. Often the ohms per volt or FSD ( Full Scale Deflection ) of the meter is written or printed on the face of the meter. You use a formula to work out the value of the external resistor , in parallel for measuring current and in series for measuring voltage. Using the formula you can fit a meter that has been calibrated to measure a certain parameter of either current or voltage.

Someone from around the world tells me of a Canadian distributtor....thanks Mike. Never heard of Vintage Planet...... will surf their site...curious.

will have to go feel them spark plug wires on my CH..... 3 of them have the original woven steel mesh....but never seen a resistor added externally or inside the mesh????

I have yet to put a ohms tester on the variable control but it looks complete!!!

So the original gauge of 20-0-20 is about 1.625....maybe close enough to
1 5/8....the 1 /34 maybe the bezel???

So will order the 44 mm one from Mac AUto and make it fit like Jordan did......

Now to find that buried resistor in the plug lead!!!!!
