Of course the prev owner pitches the bike as "just had the carbs rebuilt and put about 10 miles on it since". The bike idled like garbage, indicating bad pilots. Tore the carbs out, found throttle cables at the pivot not secured, but the rest of the removal went smoothly. After taking the bowls off sure enough 3 of the 4 pilots were plugged, along with 1 of the mains, all the bowls were filthy with grit and varnish. Float height's were all over the place, none of the 4 the same height, none of the 4 the correct height. Cleaned the bowls out and blew the pilots and main jets out, set the float heights to 7.5mm. Replaced 2 bad float valves where the springs had collapsed and the pins never extended back out after being pushed in - "that's not right..." . Then went to make sure all the air/fuel mixtures were set at 3 turns out, all pretty close, except for #4 where the screwdriver went straight into the carb body. me: "wha?" and take a closer look, no screw, no spring, no o-ring - just an open hole. Imagine my joy
So popped over to Partzilla, and they show 3 different part numbers for the #5, the air/fuel screw/spring/o-ring for this California model for "screw set A" - 16016-MB0-671, 16016-ME3-003, and 16016-ME9-671. All are in stock, which while good didn't help me narrow anything down.
I need to understand the difference between them to know which I need to order, I found a service bulletin stating that the first pn is a fix for driveability - https://www.goldwingfacts.com/forums...ne-1985-a.html
The kit referenced in the service bulletin for CA, Honda 06160-mg9-742, doesn't seem to be available anywhere for sale.
Appreciate any info you might have to shed some light on this.
