1929 Long Four
Are all grease nipples the same? I can’t seem to get mine to work very well. If I put the gun on, it clicks on OK but then grease just come out between the gun and the nipple, as if the gun isn’t sealed on. Ive taken the nipple off, cleaned it, and it allows grease though when it’s in the vice and with a tiny bike grease gun but not with a ‘clicked on’ gun. They all seem blocked or something. I was thinking for ease just to renew them all however what is the thread size? Presumably it’s not a standard modern thread?
