With the problem that I posted below. $120 later I have new

spark plugs. The car runs only marginally better. They were able

to provide me with the surprising information that my problem is

either in the distributer or the carburetor. Well no f***ing s***.

God, I hate taking my car to the shop.

Frustrated,

Dewar

I took the covers of the carbs off and everything looked pretty

clean. I've never dug into the carbs before. Is there a good

reference for cleaning and tuning out there somewhere? It was

running so well right before this happened...

thanks,

dewar

take your air filter off... reach into the carb and feel the venturi...

if you can wiggle it... it's loose... dcoe 40's have a different

mechanisim to secure them so it doesn't apply to those... there's

a little set screw that holds the 45's venturi's in on the bottom...

if the venturi rattles or moves fuel flow will be screwed and it'll

drive like it's got a miss in it.. party on

that runs through the middle of the of the carburetor when

looking into it? mine feels pretty secure in there but will rotate

around freely. Is this correct?

TIA,

DCOE 45's have set screws along the bottom, if these loosen or fall out you will get misfires on one cylinder, sometimes only exhibits as "pops" or backfires on overuns.
