For years I had always looked at the Moss Motors catalog and yearned for their valve adjusting tool. (Moss is a British car parts supplier) I think the adjuster was around 40 but it seemed cheaper to just use a wrench screwdriver and feeler guage.Well, the other day I was mysteriously drawn to a yard sale in my neighborhood. I was about to leave with only a couple purchases when i looked in a box at the end of the table. I couldn't believe it but there was an old, patent pending even, valve adjusting tool. It has the two wrench sizes, one on each end and the screwdriver rotates from one end to the other depending on the size of the rocker nut. I paid a dollar for it....As is sometimes is the case, the people that were selling it had no idea what it was, so I told them after I bought it. It really made my day!
