yeah the aux acc pump is on the valve cover side of the carb but on the front lower half with a vac hose runnin to it, the one you pictured is the choke braker i think or CB, shows it in vac routing diagrams,

yea i have been checkin out all kinds of diagrams LOL.

we're trying to get a new Acc. Pump.....but apparently they are discontinued and i can't get one anywhere..

yoterr

a rebuild kit doesent come with a new rubber dealy?

camo31_10.50

i believe the rebuild kit only comes with the pump diaphragm...it might come with the boot?? i haven't gotten my kit from NAPA yet..so im not too sure..

camo31_10.50

you guyyysss...where the hell do i get new Accelerator pump?????..stealership can't get one??..im thinking a junkyard one is gonna be in just as bad a shape as mine is..since it's probably been sitting out in the weather..and therefore the rubber will be brittle...

so where to get a new Acc. Pump..or can i replace just the boot??

camo31_10.50

ya'll are slackin off again..dang guys..help me out..i need to have this bugger fixed by tomorrow..

Try the junkyard anyways for the acc pump, you never know. I had the same problem, was going through fuel filters on a regular basis, then the fuel pump died, then my carburetor started running like crap, the culprit was a rusty gas tank. I say change the fuel filter, its quick, cheap, and easy anyways, and don't be afraid to go crazy with the carb cleaner either

camo31_10.50

i've been trying the junkyards..none have any acc. pumps for my truck..lol..they got em for older 1st gen 22r's..but they're vacuum operated..mines mechanical..lol

its not the pump..lol..although the tank is probably nasty..my 2 filters are new..and the problem persists..its the acc. pump..has to be..

at least it better be..LMAO

Yotapowa

Hmm. Hopefully you can find one. And if you were thinking of a carb rebuild, I'll warn you it can be pretty time consuming and complicated with all the linkage on the back lol, but well worth it, my truck ran amazingly after I did mine

camo31_10.50

i believe that i could handle it..lol..if i have any problems then our mechanic can help me..he rebuilt the carb for my '80 and it came out great!..

all i gotta do is make sure i remember where everything goes..lmao..then put it all back together...but before that the carb body would get sent off to be cleaned..lol

camo31_10.50

anti diesel solenoid.........what the F is that..lmao..

do you mean the Idle Cut Solenoid?..i was told to just unplug it and see if anything changes..nothing changed lol..if this is what you are talking about then i will test the voltage when i get home and listen for it to engage..

still need an acc. pump though....lol..still can't find one.....................

camo31_10.50

come on dude..you can't post information then not check back with the thread..LOL

camo31_10.50

heyy...that helps ALOT (with the pic and explanation..lol) i did unplug it..to see what would happen..but i didnt test it..and i didnt get around to testing it today..lol

i will test that in the morning and report back..in the meantime

if i spray carb cleaner (while the motor is running) around the back of the carb..it idles quite a bit smoother..but wont stay idling..it just seems kinda weird that CARB CLEANER would make the truck idle better???

specifically if i spray around the back of this little bugger..that i THINK is the Idle Up Diaphragm..
the little brass lookin thing with the vacuum line goin to it
and that's where it is located..(center of pic...again..the little brass thingy..lmao)

still can't find an accelerator pump...im gonna try the Carb rebuilder places..see if they can get me one..

Alright, you're kind of on the right track, but you're looking at the wrong items.

The carb cleaner will make it run better because it's taking the place of the air getting sucked in the vacuum leak.

Check this page out, it will answer all your questions:

The better NAPA rebuild kits that take the carb tag # into account should come with a new AP, but I doubt that's really your problem. The boot is just a dust boot, and doesn't affect air or fuel.

I could tear one of these carbs down in my sleep, so post back with any further questions you have.

camo31_10.50

i think..by the time im done..the carb is gettin rebuilt..

not only do i have this problem..but if i FLOOR it..(like...suddenly from idle just FLOOR it...not gradually but IMMEDIATE) then the truck stumbles and will act funny..i cant really explain it..the DS choke will flutter back and forth..and the truck almost dies...i think it's flooding it...as in when i floor it then the truck is getting too much fuel...and my mechanic thinks that it's not getting enough fuel..LOL..

im going to mess with the mixture screw a little tomorrow too...as the cap thats supposed to be over it......isn't there anymore..so it's likely backed out a little bit and is causing the truck to run way rich...

one way i know it's runnin rich..is if i floor it..and it starts to bog down..i can let off and kinda 'pump' the pedal once and a little black smoke will come out of the exhaust..which is unburnt fuel..

so things to do tomorrow...check the fuel cut solenoid, and check the mixture..lol

camo31_10.50

ok..so i checked my mixture..and the screw was 8 full turns out...........

so i screwed it all the way in..brought it out 4 turns (factory spec..about) a she still wont idle..lol..

im gonna check the idle cut solenoid in a few mins whenever the rain lets up..lol

keep the ides comin guys!

camo31_10.50

ok guys...pulled the idle cut solenoid because i was getting power to it..but didnt know if it was working..so i took it out and to visually see if its working..and its not moving???

this is it..and BTW this is with the key on and and the solenoid plugged up..

camo31_10.50

anybody?? got any ideas??
