Quick 32/36 carb adjust question

[nbristow01]

Possible dead kittens....but air fuel mixture...how many turns out? My car has black exhaust, I smell bad, black plugs....I assume I start the car, screw the mixture screw in and the turn it back out either x number of times or until i get to smooth idle..but don't know what x turns is

I think the rule of thumb always is that you start with three full turns from all the way in, looking for point when the idle speeds up just a bit - but if your car has black exhaust and plugs, sounds like it might need smaller jets.

c.d. did a nice write up on this carb.

float level,

float level,

soggy float fuel check...

that and the power valve.

And there are 2 answers- older carbs have coarser threads,

so the number of turns varies.

Man mine was 5 full turns out!!, got it adjusted

In fact there are at least two needle 'sizes' for the idle adjust screw. The longer pointed tip is more gradual, the shorter tip is more rapid. The longer one is about 3 1/2 turns out from seated postion for beginning the adjustment. The coarser shoter tip is more rapid. I found about 1 1/2 or 2 turns for starting the adjust. Good Luck!

anyone ever MEASURE the float level

does it pull smoothly all the way up to 80 MPH ?

how does the motor react when trying to accel

from 60 ...80mph?

everything begins your motor having strong

and even compression readings, correct valve

clearance, correct ignition timing, correct float level.

Turning one SCREW isn't going to do it.

You need to start with a known base of correct

adjustments listed above - then understand

cause for any running change - what effects the motor

running during each condion. Cold starting,

acceleration, idle, consumption, restarting......

but the carb must be CLEAN, new unmolested(meaning

someone has drilled out the jets to some unknown

opening ) jets - and you need to buy a WEBER how to

book and read before tinkering any further.

Pierce Manifolds sell an excellent Manual/Parts Book

covering all Webers - Do yourself a favor and buy it.

you have a DGV carb:

FLOAT LEVEL - DGV / IDF / DCOE / DCNF / IDE-XE

The float level is a critical part of carburetor calibration.

Changing the fuel level in the bowl will change the point

that the main circuit starts to feed, alter the

characteristics of an emulsion tube, and affect

fuel consumption.

GENERAL INSTRUCTIONS: Float level, in mm, typically

refers to the distance from the face of the carburetor top

cover to the float. With the top cover held vertically (float

pivot at the top) and the float tab (Lc) resting against, but

not depressing the spring loaded ball in the needle valve,

measure between the face of the carburetor top cover

to the top or bottom of the float. On carburetor models

where it is required to remove the float to replace

the top cover gasket, the measurement should

be made with the gasket in place

to the gasket face.
