i have a 85 with a 22r, im running a weber which i just rebuilt a few months ago. the issue is sometimes when im driving i will push in the clutch to come to a stop and the truck will bog down and die. its also does this in the mornings upon start up. but its cold upon first start up and that isnt really an issue. i just dont know why it would be doing this when the truck is warm. most of the time it idles fine with the carb turned up, but it still seems to want to die. any help would be apprieciated. thanks.

help?

im having the same problems with the weber. ive taken it to two different carb shops and they both have told me that the stock carb is better. so now im putting all the old smog stuff back on. not fun.

sounds like your running rich. i don't know too much about webers though. Possible that the rebuild wasn't good, because you say it changes...possibly a leaking gasket/diaphragm?

I'll get a guy in here for ya.

85 what size jets did you use?? it sounds like either a air jet is plugged or your mixture screw is way off

79coyotefrg · « **Reply #5 on:** Oct 17, 2007, 11:15:10 AM »

no-idea, that doesnt surprise me, since "most shops" dont have a clue about how to work on a weber

again i need to know what size jets you have, pull the top off the weber and see what the number is on the jets in the fuel bowl and the ones on the other side aka air jets

85toycrawler · « **Reply #6 on:** Oct 17, 2007, 12:05:42 PM »

ok i will take a look at it, and get you the numbers. all i know is that i used what came in the rebuild kit from Weber.

im running a .460 lift racing cam and bored .060 oversize, and im running 150 primary and 185secondary

cant remember my air jets but thaTS nothing new

79coyotefrg · « **Reply #8 on:** Oct 17, 2007, 12:27:51 PM »

mine ran like poo around 3000 rpm, because i was runningtoo small of a jet,

chances are yours are too fat, or in the wrong spot

85toycrawler · « **Reply #9 on:** Oct 17, 2007, 12:31:55 PM »

ok i pulled, what i think are the jets out of both sides of the carb, and the big one says 60 and the small one says 50. any clues?

79coyotefrg · « **Reply #10 on:** Oct 17, 2007, 12:49:05 PM »

those are the ones down the throat by the stud that your aircleaner bolts too??

85toycrawler · « **Reply #11 on:** Oct 17, 2007, 12:53:36 PM »

i believe so. there is one on each side. one big screw, and one a little smaller.

79coyotefrg · « **Reply #12 on:** Oct 17, 2007, 01:01:50 PM »

ok, did you have some other jets for those ports in the kit??

also pull the top of the carb and get the numbers from the jets in the bowl

85toycrawler · « **Reply #13 on:** Oct 17, 2007, 01:08:12 PM »

no, there was only the 1 that hooks to the float. i will check the number.

85toycrawler · « **Reply #14 on:** Oct 17, 2007, 01:15:37 PM »

ok apparently im an idiot. the thing that attaches to the float is not a jet. there are 4 other jet looking screw deals. 2 in the bowl and 2 above the bowl. the 2 in the bowl say 140 and 1 of the upper ones says 160 and the other says 170.

should have two brass jets in the bottom of the bowl over on one side

85toycrawler · « **Reply #16 on:** Oct 17, 2007, 01:16:21 PM »

yeah, i found them. im an idiot. those say 140.

79coyotefrg · « **Reply #17 on:** Oct 17, 2007, 01:34:55 PM »

ok and your motor is basically stock??

ok have you checked the mixture screw, its the screw on thebase of the carb, with a spring under it, run it in till it stops but as you do count the complete revolutions of the screw , then back it out 1 full turn

85toycrawler · « **Reply #18 on:** Oct 17, 2007, 01:46:31 PM »

ok i will try.

85toycrawler · « **Reply #19 on:** Oct 17, 2007, 01:47:40 PM »

ok i did it. now any other suggestions? and yes the motor is internally stock as far as i know.

79coyotefrg · « **Reply #20 on:** Oct 17, 2007, 02:02:59 PM »

use the slow idle cam, its the one that you should idle with when the engine is warm, adjust the screw till it touches the cam, then 1/2 turn

fire it up and adjust THAT screw till it idles decent, then to smooth it out back the mixture screw out till it idles better then back the slow speed cam screw out to slow the idle, do this over and over till it idles aroun 850-900 rpm

85toycrawler · « **Reply #21 on:** Oct 17, 2007, 02:06:15 PM »

is the slow idle cam screw the one that attaches to the throttle linkage? and also has a spring under it?

85toycrawler · « **Reply #23 on:** Oct 17, 2007, 03:08:55 PM »

ok, thanks. just making sure. as you can tell im a little new to all this.

85toycrawler · « **Reply #24 on:** Oct 17, 2007, 03:42:14 PM »

thanks again for all the help. i put it back on and it seemed to idle fine after a little tuning. i will keep you posted on how it does going down the road.

ninja turtle · « **Reply #28 on:** Oct 17, 2007, 08:09:33 PM »

you are very kind glen. the stock is back on, getting it smoged then putting the weber back on. once its back on im sure i will need some help. also, i think your right, the two "carb" shops i took the truck to didnt seem to have a clue. anybody know of a good shop in the reno/tahoe area? i have tryed a lot over the 11 years ive been driving without much luck. thanks glen!!!
