Quadrajet Carberator

[74 C-10 Shorty]

It's not leaking and it's pumping fuel don't worry about it, one thing at a time just do a "complete" tune up first.

Thanks for the help buddy. I will let you know when I get the plugs and wires in and take er for a rip. I hope I wont be cutting 40 mph wind today

[74 C-10 Shorty]

Anytime glad to help, don't forget with HEI plugs are gapped at .045.. And check cap and rotor I'm sure they need replacing too.

[Steve341]

Best I could find was champion wires and Bosch platinum plugs

[Steve341]

These champions should be better then these Whitaker plug wires that's on it now. They look OLD wondering if they were from factory

[74 C-10 Shorty]

Couldn't find Autolite???, and here I thought I was in a hick town that didn't have anything,LOL, you have the small tapered seat plug right?, and nobody had 144's???, Bosh will do fine though.....

After 15 years under the hood anything looks old,lol, new ires should do wonders for it...

[Steve341]

I googled these Whitakers. They are vintage 60s and 70s wires

[74 C-10 Shorty]

Sooo, got er all tuned up yet?..

[Steve341]

Just put the plugs in. They all had oil on them lightly and black carbon deposits and #7 had real bad oil. Since I put my new carb on the cold idle sucks. How can I fix that

[Steve341]

If I press the choke open with my fingers it runs not bad cold

[Steve341]

Once it warms up abit it runs beautiful

[Steve341]

Nope still there.

[74 C-10 Shorty]

Sounds like choke adjustment, is it electric or heat coil from the intake???..

[Steve341]

Heat coil. The hesitation is still there during accelerating

[74 C-10 Shorty]

Take that cover off and clean out the cavity and make sure the coil is not broken and clean, crud builds up in there over time and can make it non functional.... Is your timing right??, set total at 36* and all in by 2800-3000rpm, if it still stumbles then it's the accelerator pump, if it's 15yrs old  then odds are the carb could stand to be freshened up too..
