If you remember my thread from last week I was having issues with my 1965 Mustang with a worked 351W not running smooth at a steady speed which eventually over 10-15 miles got much worse. Idle and WOT seemed fine. I determined that I have good spark and good fuel pressure to the carb so now I'm looking at the carb. I figured I would check the floats first since that should have been the easiest thing to check. Primary float was good. Secondary float was off as the fuel level was way too high and it was pouring out the sight hole so I immediately plugged it. Well, the manual didn't say to drain the bowl before trying to lower the fuel level. Apparently the adjustment doesn't work right if you don't drain the bowl. I kept turning the float adjustment nut (yes I did it in the right direction - clockwise) and nothing seemed to change because I didn't drain the bowl. So now I realized that all my turning must have tore the gasket because you know what it's not even there (or else it was never there to begin with ???).
So here are my questions.
If the screw threads directly into the valve and the screw sits directly on the nut that sits directly on the carb, how does the adjusting nut work and why does the gasket make the difference? The nut doesn't appear to have any threads and the gasket is what makes it work? Now that there is no gasket the nut just wobbles all around.
Can I completely unscrew the screw to get the gaskets back in or will I not be able to get the screw threaded back into the valve without pulling the bowl off?
