Rundown of what is going on:
So... I saw this 2000 Kawasaki Vulcan on CraigsList for $1200... The Seller said it ran smooth, it just leaks fuel between the cylinders... (oh no! - easy fix but I didn't tell him that lol) ... Bought it for $1000 and got 2 free helmets and cover.
Or so I thought... I knew the overflowing of gas out of the carb exhaust ports was due to sticky or incorrectly set floats. When I finally managed to pull the carb out and get it disassembled, I was presented with a sobering fact that I in fact DID buy someone elses problem and grief... for $1000 bucks no less.
The damn float bowl had pockets of green sludge
(almost like wet flour, but not as wet or gooey) that was accumulating in various corners of the float bowl as well as causing the float needles to be extremely stuck.
I got the float bowls all cleaned out, the needles unstuck and cleaned, the needle ports cleaned ... I sprayed Gum-out Carb Cleaner in every crevis I could find whilst avoid gaskets and hoses the best I could.
So I put everything back together, slapped it back on with fresh gas and it came alive only for a second or two. I turned on the choke (and ended up snapping the cable in the process after repeated use), it would turn over and start and run for about 3 seconds then quit. I used starting spray to give it a little something to feed on and maybe fill the bowls and even then it wouldn't run for more than a second.
Upon further inspection, I noticed on of the float bowls was set extremely low, and the other was high. I have no clue where they should be set, but there are 2 extruding lines inside the float bowl in the same position on both sides and I'm not sure what those are...?
I also noticed that on one carb, the A/F was out at 2 turns and the other carb was in at only out a half turn.... wtf?! lol.
I have a few questions to hopefully get this carb back in functionality....
- What are the 3 holes at the mouth of the carb that attaches to the intake?
- What is the recommended turns out from stop for the A/F ratio screw?
- What is a good float height to set?
- Does altering the float height have any effect on running lean\rich?
I've read how to use a home made manometer, but I've no idea how to adjust the vacuum? The problem with this thing running ALL resides in the carbs. I'm curious if spraying Gum-Out Carb Cleaner in every crevis is good enough to get functionality back to allow me to get some seafoam\stabil in to the gas?
Any hints, links, solutions or ideas is welcomed!
