Always ran good back in the day. Tune it right and it runs.

I used CP 30% and an Enya #4 - idled better for some reason. Runs great. I recall I did blunt the idle needle some to richen up the lower end.

I found two such needles ? One is not tapered at all and the other is. They both look stock. Might have been an update. I will mail them to you for free if you PM me your address.
