Carb tuning, larger accelerator pump nozzle?
Too many changes at one time crossed my mind. As an Engineer I know that's a "no no". I am keeping a log of changes and noting the effect(s).
Thank you for the info, that really helps.
The stock IFR are 0.032 stock and that's what I made to go back in when lowered.
You make a good observation/point on the transfer slot exposure. Right now the idle is set to about 900, I can lower it to about 750 and get 13 to 15 in/hg of vacuum. I did install a secondary external adjustment screws, as of now the transition slows on the secondary are closed. Doing some reading opening the secondary's to allow less primary exposure seems to be hit an miss on weather it is a good idea or not.
I think for right now I may leave it alone and drop the idle and see if that has an effect. If it does I may reset to stock (leaving the lower IFR) and move the E-holes per
@mderoy340 (who I forgot to add to the conversation, sorry my bad) recommendation and reassess.
