vacuum gauge to solve idle issue

Well got home and fired up the cuda. Neighbours weren't too happy but it was only 930, late but not drastic lol. Fired up and immediately went to 2000 rpm. let it warm up sprayed carb cleaner around base looking for vac leak. Couldnt find one. Dialed in idle screws while.running to stall engine but wouldnt stall out lol
Removed idle screws sprayed with wd40 and carb cleaner amd a quick blast of air. Snugged screws in then out 1 1/2 turns.
Fired right up, lowered idle to around 850 and runs good.
A quick set of timing to 15* and then out for a rip.
Still need to tweak but WAY better. Its drivable lol
Thanks all!
