Picked up a 4200 for cheap it has no spark, it has the phelon 2 piece ignition I found a service manual how to test the ignition system which was mostly testing wires and the kill switch. I tested the primary and secondary coils and I think the secondary with the spark wire is dead. I tried baking it replacing the spark plug wire and cleaning all the grounding surfaces. My questions, am I right about them being primary secondary coils? And does anyone know a way to fix or a cheap replacement? Thanks appreciate any and all replies

No cheap way around fixing that, that’s why you got a deal, lol. It’s usually the Poulan 5300 39067 module that fails & not the 5300 39068 coil. New old stock modules sell for $50 up to $75 on the website auction sites. Coils go for about the same, so $150 for the pair.
Poulan called the coil a “transformer”, it has the primary & secondary windings in it & can simply be checked like the old points coils. Expect to see 1.5-2.0 ohms on the primary & 7-10k on the secondary plug wire. The Homelite XL-925 also used a 67164-A coil that can be modified to work on a 4200, but they’re $75 too.
The “ignition module” has both the voltage generating laminations & the solid state trigger combined.
When compared to modern “all in one” ignition modules, Poulan & Homelite split the functions into two devices. Likely there was not enough room for the rather large single ignition modules available at the time, before electronics were miniaturized. Now the solid state modules are tiny & more reliable, if they don’t put them under the flywheel…
