question for 1st genners about smoke screw
 

has anyone ever put a longer smoke screw in?

i just took my afc spring out, does about the same thing. you have to contol smoke with your foot instead of the afc doing it.

doing this lets you fuel pin drop all the way down = full fuel all the time

would this cause issues with the factory automatic? overdrive that is

some people take it out and tack a little extra weld on the end and then sand it down to shape

I think your thinking of the full power screw.

No reason to extend it, All your gonna gain is smoke and no power. Removing the spring can actually hurt bottom end performance. Too much fuel to soon can put out the fire and cause poor performance and slower spool up.

im glad i asked before just doing..hahaha

taking the spring out really does hurt low end performance, my truck diesnt want to spool well after i turned the full fuel screw(it was only a turn but still) If your truck is all stock just take the spring out because my truck ran pretty good on the low end with just the spring out.

You can use teh smoke screw to gain anything you will with no spring and still retain full AFC function.0

with my denny t pin i used a 6mm washer between the fuel pin and the metal part of the diaphragm to shim the fuel pin down... i also machined the afc tophat to get more travel upward but you apparently dont want that anyway.

i sanded the little plastic washer to about a 1/16 of an inch, i didnt notice anything tho
