I hate carbs... But I can fix one if I have too...
Don’t know about gallbladder surgery, but an ACL replacement/Meniscus sew-up/ MCL sew-up is not very fun either. I have a new respect for ice packs!
Rebuilt a 2 barrel carb about four times on my old Chevy Vega, back in the day. That thing never did work right at idle. Drip, drip, sputter, sputter.
One rule of thumb I have been able to remember is running a mixture screw in to close and back out 1 1/2 turns to be close. The little 2100 on my 304 has one mixture screw that is a real pain to adjust without one of those flexible screwdrivers.
A blown gall bladder is a special brand of misery. Abdominal pain on par with a kidney stone, turning very yellow/orange all over, dark brown urine, and an overall since of misery.
