Ok I took the top off of my mixture unit and determined that my screw in infact present, I think, maybe. Actually I'm pretty sure its there but its so striped out that the head is nearly unrecognizeable. For a 1 in a million chance I filled the striped out hex hole with JB Weld and am letting it cure with a 3mm wrench (wrapped in saran) in hopes that I'll be able to recreate a usable head. I'm highly doubtful that it will work so I'm in the market for a new screw, unit, whatever. If you've been following this thread and are having a hard time viualizing this pesky screw/airflow meter/balance arm then turn to your books and follow along page D:01:05 and you'll what Bill described. The two arms are spring loaded together and the screw simply pushed down the plunger arm changing the relative agle of it to the balance assembly. The bottom of the screw is the flat washer end so its threaded up from the bottow originally before assembly making it impossible to remove. It does nothing though to prevent a previous owner from destroying the head of the screw! :) Jeff 10544 To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
