Nick-
Start with a copy of 75 Tips by Bruce(VA), the ESSENTIAL MANUALS, and copy of JMOR's WIRING PICTOGRAMS, the latter in our HOW-TO's forum. The best tool you can invest in are at least the CLYMER I&T FO-4 manual, and the 39-53 Master Parts Catalog from Just8Ns. Don't assume just because you have a 12V battery it is wired correctly. A GRP 25 or 35 12V battery with good 12V cables is required. A 12V 9N/2N conversion also consist of removing the GEN and CUTOUT and replacing with an ALTERNATOR, belt tensioner, new/rerouted wiring, 12V lamps, and uses the OEM Ballast Resistor. If a 6V coil is used you will need to add an external 1-OHM white ceramic resistor also at Just8Ns. If a 12V coil is used, delete the extra resistor. Front Mount Distributor is tuned up off the tractor on your bench. Use the manuals to see how to set points and TIME it -you don't use a timing light. DIS is mounted only one correct way. If off it will bust the aluminum base and become junk. There are but 2 or 3 GOOD brands of points nowadays. Seek Standard Ignition/Blue Streak #FD-6769-X and can be found at NAPA as well a s all the other parts for the front mount DIS. Don't let them sell you the ECHLIN brand. They used to be the best but now are junk. TISCO and CASE/NEW HOLLAND also have some but the latter may no longer be supplied. OEM Spark Plugs are spec'd as Champion H10, but since the Champion H12 (512)and AUTO-LITE 437 (216) were made as a hotter plug and either one will work fine. Never leave your IGN key switch ON -it'll burn up the points. Points gapped at .015", Plugs gapped at .025". Firing order 1,2,4,3 CCW. Use OEM Manuals for parts and 6V/POS GRN setup. Only JMOR's PICTOGRAMS have the 12V conversion.
