Coils

The part number you're looking for is 55986-A



Back to the points box.
 
If you plan to use the kill switch, you'll need to attach the ground wire to the points post. The part number is 55990. Or, just whip one out with 2 ring terminals.


On the back side of the box use the felt seal. It's there to keep saw-dust out of the critical areas. There are a few versions. I believe the R82 took this style. The part number is 55989.



Some points boxes secure the coil ground on the back with a screw. The ground is very fragile. This box is set for a hybrid R95 built from some mixed saw parts.



I don't have a way of measuring capacitance, so I just have to trust the used and NOS condensers work until proven otherwise.



Here is the condenser part number



Do what the timing cover says and gap the points at .015" or .020 (according to the Hot-Rod manual). The points cover itself is .015" thick and works great to set the point gap.

Unlike the MC engines, you don't need to set the rotor gap because the coil mount is fixed.



I used 6-32 X 5/16 slotted FH screws to replace the same size Homelite screws on the retainer plate.
Instead of using the factory fillister head screws for the coil, I used 10-24 X 7/8 and 10-24 X 1/2 SHCS. Torqued to 80 inch pounds.
 
You should be able to turn it over and get a hot blue spark about 3/8" long.
