Im on the road with the stang jets 64 ill report back

He has a ford 302 F150

Im doing this it makes sense Published on Sep 28, 2012 everyone has always complained about these being highly untuneable. i have had two and agree but have located the problem. this is an explanation of what i show in vid please read!!!!! There are 3 problems on the Street Avengers that cause the stumbles and hesitations: 1. Lean Jetting. The S/A carbs are jetted very lean on the primary side, and extremely lean on the secondary side. Bump primary jetting up about 3 jet sizes and then make the secondary jets 8 sizes larger than the resulting primaries. To save a few bucks on jets, take the jets out of the secondary side and install them in the primary, and then just buy a pair of jets for the secondary side. This gets the carb jetted about right and will do wonders for throttle response and power. 2. Accel pump lever not touching pump cam. I see this constantly on the S/A carbs, and it's really lousy assembly work at the factory: The accel pump lever that connects between the pump cam and the accel pump arm does not ride on the pump cam at idle. The lever is riding on top of the throttle shaft spring and is not touching the pump cam. Only after you rotate the throttle a bit (with no accel pump action) will the pump cam touch the lever and produce a pump shot. To fix this, remove the lever and bend the lever a little more right where you see the "kick-up" bend in the lever where it's supposed to ride on the cam. By giving the lever more of a bend, the lever will not hit the shaft spring and will ride on the pump cam right where it should. This will produce an instant pump shot off idle, and will solve most of the hesitation/stumble issues associated with these carbs. Keep in mind that you will need to re-adjust the accel pump lash adjustment after you bend the arm. 3. Inadequate secondary idle speed setting. On most S/A carbs, the secondary throttle (idle speed) is fully closed. This causes the primary idle speed setting to get cranked up too far in order to achieve a reasonable idle speed, thus exposing too much of the primary transition slot. This, in turn, will cause an off-idle stumble due to lack of transition fuel enrichment as the throttle is opened. The primary and secondary throttles should be open the same amounts at idle - they should be balanced and see equal airflow. Forget about swapping pump cams and accel pump nozzles - that's not the issue, and it won't solve your problems. Fix the pump lever geometry instead...

Red almost disapear :) The smell has gone away 64 jets 4160 54 front 64 back on avenger

had some hessitations at cruising speed when I stomp the pedal at 40 miles cruising at 65 the jets are 54 tomorrow Ill try the 64 and see the cruising at the AFR Im runing 12 initial timing

hahahah Ill will its yellow towards rich Ive set the idle with vac gauge Ill do the timing stuff and report back

Installed the: new 1 port vac can holley avenger cotton performance filter the AFM is in yellow "Ideal" at idle should I plug the vac can in the vaccum port? how much advance?

just conect it like it says on the back of your alt, they have img wich is wich, Ill take a pic for ya if you dont figure it out, I did add a ground cable but my past alt had only 2 wires only a red and a orange the red one I used a loop conection and secure it with a nut "from my older alt" the other one I put it on the same label as the old one

I havent do it because i love my t5 but let me look for the link bro

Its adapted

A guy is adapting one fom a japo car

oh I assumed it was like underdrive pulleys

did you gain more HP?

Yep ∆∆∆∆ I think ill put important stuff in the first page, w follow ups

what are the pros and cons on a 302 stock alternator just curious

4160 holley classic 600 cfm, i have an avenger 570 that need to clean up, knn filter, 1/2 in spacer, aluminum rad & electric fan, thats going to be installed, i dont think im gonna upgrade anything more on the engine for a while

4160 vac sec they geve it with no choke plate, I dont think it had any mods, the avenger is stock but havent got any time to put it and tune it,

Full rich acelerating Driving in the city leds are on green orange and red, before it always was on green Driving at 1500 rpm 5th geat at 65 mph the led is lean but it wont dissapear in the gauge

rich when flooring or acelerating cruising is moving cruise on heavy gears is lean no stumbles

Wont disapear, it will stay on the last one in 5th gear, in city wil dance from green to orange The guy just sent me the new can because it was out of stock so ill have it by thursday Yes i floor it, works great I was told that the avenger will feal a lil stronger and responsive What would be my max degrees With the vac?

it responds like a champ! a whole different car, do Im gonna need a vac can?

Got a T 5

Do you think i should gwt the avenger? Its free in almost new cond

Ill test the last one today and report back
