basically you are supposed to turn that screw counter clockwise to bring the RPMs down, well that's all well and good except the screw is in there all upside down and who knows what clockwise or anti clockwise be, so basically just loosening it or unscrewing it makes the RPMs go down and screwing it in makes them go up, (in theory)
you see I spent a few days trying to tame this little rascal, see the most you can turn that screw is half a turn at a time cause the carburetor and such is in the way, so what The Greg would do is use a 1/4" box wrench and give it a 1/2 turn (as much as possible) then start the car and see where she idles, then the next day, (after a proper cooldown of the enjin) I would turn her another 1/2 turn and see where she RPMs and after playing that silly gave for a day or three, I said enuff is enuff and I unscrewed that darn screw flat all the way as far as it would go without falling out, I had to see where it would RPM with it all the way out, you know the extremes from one end to the other, and I gotta tell you that even all the way out she still RPMs at above 1200, see there the pic well I wouldn't be writing about this if it don't surprise me none you see, cause now I need to turn the screw back in some to get that 1500 sweet spot, but it aint all as easy as them marketing guys make it out to be, especially for such a small tiny little screw |
Re: Restoring Rusty
1200 is a little low. I usually set Fast Idle at 1500-1800 RPM and Curb Idle at 700-800.
You should be able to swing the fast idle cam over the adjustment screw and set it even after she warms up. |
Re: Restoring Rusty
so from all the way out to half a turn in I think I dialed in my Fast Idle to around 1500 RPM

time to get this situation rectofied real quick
now some of youz might ask now Greg why didn't you replace that output shaft seal when you had the transmission out and on the workbench, and to you I say... [who made you guys the efficiency police, lol, ha ha] it's so much more fun doing it on the truck, well under the truck well under the now lowered truck first we go out and git the a proper single purpose seal puller "guaranteed not to mangle the old seal as you pull it" we'll see about that |

after raising the rear end of the truck sky high to prevent any seapage, we snuck up on the seal and in no time she was out

and in what seemed like no time at all, the much lesser known Seal Team 5 had the new output shaft seal pressed in and ready for action
test drive done, and Leakage Report at 11 |
Re: Restoring Rusty
Now we have been schooled by the Greg ,good deal .But Chevy's still seem to find a place to leak just to give us something to do.
|
Re: Restoring Rusty
Chevy's don't leak .. They just mark their territory.
|
Re: Restoring Rusty
Chevy's don't lose oil. You always know exactly where it is.

One in this kit should work. https://www.holley.com/products/fuel...ies/parts/20-2 https://rspimages.holley.com/20-2.jpg?width=583 |
Re: Restoring Rusty
Whoops, I was wrong about the hole I've used. My 6-cyl throttle cable wasn't long enough, so I used a Lokar cable and bracket that I had in the shop. Lucky I wasn't able to sell it at a swap meet!

Re: Restoring Rusty
Every time I see the stance on this truck I break inside a little out of it's beauty. Then I remember you want to lower it because it's not a 4x4, and find myself cringing. But to each their own, and as always an amazing thread.
P.S. At least she's not slammed. :metal: |
