I rebuilt the CCC Qjet on theTA last night.
It won't idle. it's getting fuel without it comeing through the idle circuit. the screws are all the way in, and it's still sitting at 1750 rpm with the choke off.

In addition i've got a sunday morning brain fart, I can't remember which side of the dwell meeter's rich and which is lean. when it hits closed loop, it's sitting right around 50.... open loop about 20
which if i remember is full rich.. but alas.. i cannot remember.

I'm thinking i screwed up the lean stop adjustment on the Mc solenoid plunger. basically cause i don't have the little measuring device, and if it was set too high, the rods' woud allow fuel flow.

other question is, appox how deep should the Idle air bleed screw be set.


Ruled out Vacuum leaks.. it's getting fuel somewhere where it shouldn't, either that or the throttle blades are somehow open.

Thanks

 

I've got the lean stop adjusted properly now.

The present problem is such.

The idle is slightly high. The idle screw is out to the point where it doesn't contact the linkage, the blades are shut.

I started with the Idle screws out 2.5 turns.

dwell meter indicates at idle that it's full rich, on the MC solenoid.
There are No vacuum leaks.

with the screws out 3.5 turns, still full rich on the solenoid. but i'm unsure and quite convinced the idle air bleed is badly misadjusted.

Anyone have any insight on how far in the idle air bleed should be.. appox number of threads.. depth from top, would be apriciated.

it's a stock lg4 with a performer intake.. so it's air demands are not much, if at all greater than the factory settings.
Thanks
