Sorry for the lack of help guys, I work for a living and have less time these days than I used to have for answering questions due to the wonders of downsizing.

Now about fuel coming out of the carb, a fine mist or a few tiny droplets while running is nothing to worry about but a big drops are an issue. We need to know which is it is. The spring in gut regulator could be just old and not giving you the proper pressure. Do not think that stretching the spring to give you a little more pressure is good idea...it's not and you will drive yourself nuts. I bought a used YS years ago and never paid attention to the spring and it was giving me grief, sent it to Richard who did nothing else but swap out the spring and it ran like a top.

What are the settings on you HS needle, LS needle and where is your regulator set? Flush, above, or below the housing? The regulator controls the total VOLUME of fuel to the engine. the HS needle cuts the amount back to what it needs for WOT and when the engine transitions it needs more fuel volume to keep from going lean. Remember the old carb on you car had an accelerator pump to help for just this reason.
