the procedure is to have the adjusting screws completely free.make sure both
front and rear are completely closed.if one of the front set is not the xact
same as its' mate there will be no adjusting possible.and ditto for the rear
set.if all are closed properly.screw back the center adjuster first the the
double adjuster screw.now screw in the double adjuster which engages both
front and rear till it just barely kisses it's tab.now check if all are
completely closed.there is a certain screw cap in the top of each of the four
the see with a light where the butterfly sits.only now can you start
adjusting.turn each idle screw in gently till it sits then turn it out two
turns.if the car does not start turn in the middle adjuster till she starts
then when she's warm turn the screw back till the idle is 900-1000 rpm.now and
only now can you use your vacuum gauge.you check front and then rear and if
they are not in line you must turn the double adjuster (where the little
spring sits) a quarter turn at a time anf then check after each adjustment.it
may sound complicated but once you do it once or twice it's a piece of
cake.another factor is the fuel pressure cannot be more that 5psi.

Gentle Alfisti,
A brace of DCOE4 carbs are proving difficult to balance and I want to get them
just right. So I cobbled-together a manometer from two vertical plastic tubes
and rubber stoppers and am drawing vacuum from the brake booster inlet and the
mirror side opening inlet on the adjacent carb. I fiddled with this
contrivance all morning and I still cannot get the carbs to exhibit equal
vacuum. Please, Digest, tell me if the opening of the carb butterfly by means
of the central balance adjusting screw will increase the respective vacuum in
the system downstream from the opened throttle plate. Or is it the
other-way-around?B In other words, will putting the throttle plate on it's
idle stop ( fully closed) increase vacuum at the downstream port?B Does the
brake booster air valve effect the results of my comparative balance test?B
Thank you one and all.
