Here's a question...are you setting the 30 degrees dwell with the air clear lid on or off? As I just checked it and there is a 10 degree difference with it on > goes to 40 degrees. I just reset it with the cover on for 30. UPDATE > around town, idle and off-idle engine runs even better!:happyanim:

99% sure mine does...I'll check it out Sunday.

Hmmm interesting > tell me, does your test pipe have the bung welded on the side like the OE converter? And I wonder (if) there is any difference from 80-81 C.Converters length/bolt patterm that is. PM me your price.

Hey people, for my 81 where would you suggest I purchase an 'off-road tube' that will be a proper fit? Also, I believe some off-road tubes already have a bung welded in the side too, correct? Emissions exempt here, well under 5000 miles per year and will only use it off-road :chuckle PS also...

Thanks for the explanation Peter...and very well said. Once I got into the carb I had a better idea of hoe the thing works. I'll still be a "Holley" man till the end. Engine is running amazingly good > almost too good to be true.:ugh :D Again, thanks to the good people here for all the support...

UPDATE...engine is running better than I can ever remember :thumb :happyanim: Kinda has me wondering...what's next :ugh :D

Done deal...Dwell is hovering at 30 +- 2 and good enough for me > (1.25) turns out from fully seated) I can tell the carb is very close as when I give it a 'slight' whiff of starting-fluid the engine pretty much does nothing, where as before the carb rebuild the engine would rev-up hard cause it...

Details man...details!

Absolutely and the choke slams shut...but the noted problem persist :eyerole

Same here Pete...first start of the day it idles low and a tad rough then...wham... she kicks up to a smooth high RPM for a few minutes and after driving it kicks back down to a smooth 650 RPM (in gear). I was in the electric choke unit and all seems good and the linkage is all free too. Let me...

Hi Peter, I was hoping you would respond...no special tool needed for the "Lean mixture solenoid adjustment screw" (the tiny funky head screw) as when I had the carb apart I simply put a slot in it so a small screwdriver works just fine :thumb I did find out the funky screw needs to be 3.50...

Hi people...if some recall I was having all kinds of idle issues well...I finally purchased and installed a rebuild kit from Cliff's Performance Q-Jet Carburetors. It's on the car and running better however... Two questions about these two adjustments below V 1)Lean mixture solenoid adjustment...

I went with my usual blend....two bottles of GM additive but this time with Valvoline Performance limited slip gear oil (non syn) 90/140 (or whatever) and the rear loves it. Thanks for the feedback :cool!:

GM Brand Limited Slip Additive? Just asking if anyone has used another brand of additive...or...maybe a gear oil that already has the additive in it? I've always used two bottles of GM LSA stuff when changing out the oil >anyone else use more than one? Thanks, Ray

Not when I let of the throttle...only a rough idle and mostly noticeable when it's in drive/reverse >idling. No surging, hunting of the engine off idle. Thanks for the info and all the suggestions from everyone. :beer

Wires not that old, new cap/rotor last summer. If a plug wire was faulty it would certainly show off idle, it's smooth as silk there. Thanks, Ray

Well, I hoped by replacing the cracked vacuum T and the other few 'questionable' vacuum lines I would fix or help the rough idle. No so lucky...now questioning (if) I should spend the money for one of Cliff's rebuild kits or, just remove and replace the OE dizzy and carb for non computer...

Sorry I wasn't more clear...I'm aware a battery disconnect clears any codes. After reconnecting the battery I did take the car for a substantial drive. Upon returning home, I then checked for codes...nothing came up. After I replace the busted vacuum-T I'll take it out for a drive again, and...

Update...of sorts Few weeks back I did speak with Cliff's Performance Carbs...one thing's for sure > (if needed) he's too busy to even work on my carb until the end of next summer! Very knowledgeable fellow and to my surprise is ALL FOR the E4ME. He feels my problem is a LEAN issue and from my...

Now that the Holidays are over...it's time to get back on track with making my 81 run good.
