I would change all the plugs and start from there.
The carb was adjusted fine before the trash in the needle and seat. I would not be messing with it until I looked at other things that don't involve messing with the carb adjustments other than reseting the float level of the rear bowl. |
I agree with changing the plugs - thought you had. Check you are not on a seven grade and if you are on a six if tou are changing try a five as often 6 is too cold for anything but track use if you want an efficient bur.
Unfortunately leave alone - the reality is that settingsdo not behave that way - mine was set up on Tim Adams Rig and I kept the original settings. Car has sat for over a year and the carb cleaner had to come out. Logged it on the Innovate with the laptop this weekend as it was tickling the back of the troat. Way off to say the least - only 1/8 turn on the primaries were needed to bring it back. On the Holley rig set up is done to set the idle, intermediate and high power circuits. This is where you need to be clear that the needles do absolutely bugger all in setting and mixing the mixture, This is done with the bleeds, jets and emulsion tubes . If that hasn't been done then its either been uneccesary or the guy dosent know how to set up a Holle and should leave well alone. Idle screws are simply that and are just for tinkering and tickover/low cruise - as soon as you primary circuit kicks in they are all but irrelevant.
The important thingis to check the startup circuit - calibrating the butterflys against the transfer slots an dcleanthlines.
Setting up the idle screws really is something goofy with a vacuum gauge could perform
No direspect meant but it is that simple.

Webbers are the worst - I used to do the DCOE's and IMP series on the twin cams. Fantastic when set up, but within a season they were way off.
Timing is the same you set it up and it should never change - ye right.
