Diagnose a Quadrajet carburetor problem / Re: Bog From Dead Stop
« Last post by BanditRich on August 17, 2019, 01:06:50 PM »
OK I just watched a youtube video I know where it is. I thought I took the gasket out of the choke housing I will check next time I get under the hood & check the voltage if there isn't one in there.
I can't wait to adjust the secondary spring tension so my TA launches the way I know it should.

Did you verify voltage to the choke?

Make sure that you didn't put a gasket under it, it needs to ground on the housing.

The secondary spring is easy to access with a tiny flat tip screwdriver.  You'll need to loosen the allen set screw under it to make adjustments......Cliff

I adjusted the electric choke but it still won't kick down. And I must be blind as a bat. I see the air valve spring in the diagram in the pamphlet of carb adjustments you sent me with the HP kit but I can't locate it on the carb. Where exactly is it? Could you or someone else please post up a pic?

"Do some full throttle testing from a dead stop.  It should come in clean without any stumble/hesitation or bog.  In most cases when it does those things a little more spring tension is required.  If it seems to "lag", try a little less spring tension. "

Cliff are you referring to the air valve spring or the choke pulloff screw? And what you said about getting the electric choke to work properly  -  I just loosen the screws and turn it?

The most idea scenario is to launch without any spin at all, so tune for the smoothest transition and quickest acceleration even if it's not spinning the tires. 

If you put big enough or good enough tires on it then no doubt it's going to be hard pressed to spin them w/o "power braking" it.  Those engines don't have much going on for low end torque, especially the ones with the bigger chamber heads and 7.7 to 1 compression ratios.

Even the "HO" 400's topped with 6X-4 heads were barely over 8 to 1 compression. 

Compression is power (torque).  Low compression engines, especially smaller CID never make much of it, at least at lower RPM's.....that's just the way it is with these things.......Cliff
