I have always run a slight preload on my pump cam. Always, for decades. It's the only way to properly do it, IMO. And the only time I've ever had gas drip from the boosters it was a result of the floats being too high, or it being really hot and I had winter gas in there so it perc'ed out. Usually it's a combination of 1) float height; 2) underhood temps; and 3) gas quality.  |
