Perhaps I should have sent them off to Bing as recommended! But now that I am in the middle of it, perhaps one of you all has an idea. I ran the engine today, first time after rebuilding the carbs, and got the idle mixture adjusted so it ran OK. I'm not sure the enrichener worked very well. After I got everything warmed up and running smooth at low to mid RPM, I taxied out for a runup, and at about 4500 RPM (this is a 912UL) it just dies, then runs again fine at lower RPM. At about 4000 to 4500 it sounds just weak, not quite right, then it quits. Back at the hangar, there was gas in the overflow bottle, first time ever. Now, I think I know my mistake: The enrichener disk has a keyhole shaped hole on one side, and 4 little dimples opposite it. I think I put this together backwards, with the keyhole at the bottom. The illustration in the Bing manual appears to have it near the top. What do you all think??

You will see my album on the Lockwood 9xx school. Toward the bottom of the first page, there is a pic labeled "The inside of the starting carb." See if that shows what you need.
