Oh, look out, run, Here comes Arn carrying his "my british car didn't leak" banner!! nyuck nyuck

As the good sergeant used to say, "I hear NUTTING..."

I tried 3in1 oil , 10w 30, ATF and 20w and the only issue I've had is the well runs dry quickly and so I have to keep adding with the eyedroper. I have taken these round

domed carbs apart several times and they still slurp the oil down. Does timing cause

something like that?

I removed all the oil from mine and kept a light spray, silicone or the like, on them. It resulted in a quick response. JLP

If you are filling to the threads then yes the excess oil will be sucked right in and burned.

With the aircleaner off reach in the mouth of the carb with a finger and lift the piston. Look down inside that little moving tube and you may see a line scribed around the inside of the tube, that the fill line. If there is no line, fill to within a half inch or so of the top of the tube or fill the whole tube and the puck on the rod will push the excess oil out when you install it.

Just keep in mind it is the little tube that needs to get checked not the cavity you see that has the treads in it. After that I check mine about once every lunar eclipse. Unless one is OCD, every couple of months should be fine.
