What parts to order is a sort of religious question and the answer depends on what is in your carb currently and which sect of Strombergism you subscribe to. I believe there are 2 sects worth considering. The first believes in the original seat and steel needle. The second worships the "new" style seat and Delrin needle. The neoprene tipped needle is only good for "if it ain't broke" situations, which doesn't sound like your situation. Carbs that have the neoprene needle *should* have the late style seat, but don't bet on it... Changing to the Delrin needle requires the addition of a weight to the float arm. Other causes include a piece of detritus or worn float pivots preventing the needle from closing properly. The needle and seat combos are not cheap, so you probably don't want to order something and then find out you can't use it. Also, even though the Stromberg is as complex as a rock, there are a lot of subtleties w.r.t. parts interactions and therefor I recommend you have someone skilled in the art work on it. Many of today's A&Ps are Marvel bigots and look down their noses at the Strombergs, IMHO because they don't understand them (see rock comment above...) The likelihood of one of these effectively fixing one is questionable.... So, you'll need a gasket set and likely a needle and possibly a seat, or the drain plug could just be loose... Oh, the tech list address is correct. My guess is the list is being actively moderated after the recent decent into swearing and spitting...
