Oh, well... see, another part of the issue is that adjusting it does essentially nothing lol
A while back I had trouble getting my desmogged 79 running properly, lots of issues after sitting for many years.
Anyway, as part of the process I installed a shiny, new City Racer Fuji carb, to replace the PO's non-working Holley, thinking that alone might fix it.
After installing the new carb, it ran a bit rough and I couldn't get it to idle without at least some choke.
In the course of troubleshooting, thanks to help from IHMUD members, I found the following in my specific situation:
- My carb insulator had deformed over the years (compressed corners), creating vacuum leaks and necessitating the use of choke to idle. A straight edge confirmed it and a flat file fixed it.
- Not sure if my problems were related somehow to the new carb, I downloaded a FSM and painstakingly went through all the necessary internal and linkage adjustments to make sure.
- In my case there were several additional issues (bad fuel, clogged fuel lines, bad distributor cap, cobbled ignition wiring, etc.) that aren't relevant here, but made a huge difference.
Well, after all of that, it still has some hesitation that needs to be sorted out, but it now starts right up and for the first time in many years, I was able to drive it around a bit...what a blast, and very satisfying.
