Welcome to post Covid America!!!

Nobody wants to do there job
I see this across all industries. 

In terms of classic and fashionable outerwear, Lakers Varsity Jacket are the height of style. These coats are still a favorite among fashionistas, having been a mainstay of the industry for many years.

I would guess that an idle problem is related to either a vacuum or fuel leak.  You could try spraying some starter fluid around the base and seams of the carb with the engine idling to see if you get a bump in RPM.  Fuel leaks may be harder to deduce, but double-checking the float level is a great place to start.

I have an 02 Sportster and have been having carb issues as well. Your carb is likely a Holley 4160. I can't for the life of me get my carb to idle consistently or run well in low gear despite a rebuilt a few years ago. Just ordered a new one from Holley two days ago. Luckily, if you need a new carb, the 4160 is on sale from $900 down to $625!

I believe if an Indmar your carb will be like this one:  idle speed adjustment is done via screw 175/176 in diagram.  Google Holley carb and lots of info at your fingertips.
