Jon1212 has a very nice looking 4500 with a roached p/c.   He's looking to sell it...
-Aaron

For older saws:
Tune the H side so that it 4-strokes (burbles) at WOT unloaded and just cleans up when under load.
When you lift cutting load, the saw should immediately revert to 4-stroking.  Fine tune the transition point for the wood you're cutting.

 others may know.  I'm clueless on that stuff using tester for reading.

I had another known good set to swap out to know what was bad.  Betting it is your coil and not the mod.

I bought a cs5000 parts saw a few days back, tried using the one piece ignition from it in my early two piece ignition cs4600, fit right in and the saw runs great, from what i see the one piece is still available, #156626 39732, not cheap though.......... :-\

You saying the one piece set up from 5000 will work in the 4500? Since you said 4600 I am just guessing 4500 too. Watcha think?
