I have a 1984 or 85 Suzuki FA50 that I was given. I had to clean the carb, and when I put it back together, I noticed what I though was the plug for the bowl, was actually a tapered adjustment screw.
From reading elsewhere on this forum, I found the other two screws are air/fuel mix and idle, but I cannot find anything that tells me what this screw does. It appears to allow a metered amount of gas to flow out the overflow tube up to a nipple on the side of the carb.
Can anyone help me with this?
