Timmy.......in late 1950, Ford changed from the weird 4-nipple frontmount dizzy to the more conventional 5-nipple sidemount. You can count nipples, can't you???
The weird 4-nipple dizzy has a 1-terminal squarecan ignition coil with insulative tar that melts after about 1-hr of running time. It takes about 4-hrs of cool-down or overnite for the tar to re-solidify so you can run again fer about 1-hr. Unfortunately, there is NO eazy cure for this problem. Many desperate frontmount owners "hogg-outt" the squarecan coil and wire in the more reliable roundcan coil. Remember, the squarecan coil NEEDS the MANDATORY "infamous ballast resistor" (mounted on the dash underneath the ammeter) Many N-owners "by-pass" this resistor for hotter sparkies and eazier starting. But guess what, that also causes the insulative tar to melt and makes weaker sparkies. DON'T DO IT.
Remember ittza 2-bolt, 15-min job to remove the frontmount dizzy and change the points (0.015") on the kitchen table. Just un-snapple yer capple and walk. Installation is a reversal of the removal ...except... finger start the 2-bolts and then install the rotor. Now rotate the rotor until the OFFSET drive tang fits the OFFSET camshaft drive slot. Now tighten the 2-bolts and re-snapple yer capple and yer good to go. Simple, eh?
Remember to POLISH the INVISIBLE CORROSION from between the points (0.015") after installation. Me? I clamp a $1-bill between the points and pull. Iff'n yer really cheap, tear a strip from HEAVY brown paper grocery sack and use that. ........HTH, Dell, yer self-appointed sparkie-meister
