Ok.... So I am at the garage and plugged the vac advance line. The idle did come down, but even with the idle speed screw backed all the way out, I can't get it below 800rpm.... GRRR!!

Does that mean I have to pull the carb and futz with the secondary idle screw underneath?
If so, do I back it out or turn it in?( Out would seem to make sense in this case).
And is the carb gasket reusable?

EDIT: there seems to be enough slack in the cable. Even w it disconnected 800 is a slow as it would go.

Timing an engine should NOT be this hard...

As goes everything with this Jeep, nothing goes as planned....

Figure did report where the timing was but alas, the timing tape didn't stick..... Ugh.

There are a few pics of the carb linkage in the link above. What other pics should I post?

Thanks

With it idling at 800 spray the intake area with a garden hose.

Ok... After scouring my garage I found the manual for the Holley..

It states to set idle seed with the Jeep in Drive.

That will definitely knock it down a peg or two, but I'm not going to try it without someone here to stand on the brake - no way I'm going to trust that E-brake...

I don't know if it'll drop 100rpm in gear, but we'll see.

Gotta order another timing tape...

Did you not put a permanent mark where TDC was after installing the tape? Or at least get a reference to where it was compared to the marks on the timing cover?

Unless your timing chain is really sloppy, the factory timing marks should be close enough to get an idea of where the timing is at.

IN gear with ALL lights on to load the alt some.
The rpm will drop more than you think.
For now------Set tim'n to factory OEM marks and worry about the fine tune c'it later.
BABY STEPS ......
BTW, in ans to your SA 'dial up' remark. No, DSL.

Here's a interesting question, how would the idle be set with a manual tranny?

There is a spec for what the engine should be idleing at in drive. The base idle is set while in park or netural.
I'm wondering if the hi-idle cam for the choke isn't releasing, or the screw isn't backed out far enough ( for the choke) .

Bill, and I'll answer the PM later.

At 800 rpm there should be no mechanical.


Just set timing to factory then drive it. And jet down the carb to around 48 to 45 on the primaries and move the primaries to the secondary.

Had to bail on the work last night. We had a wicked storm come through that caused a good amount of damage.

I do have a mark on the dampener where '0'
on the tape was supposed to be (the TDC mark I got by splitting the two from the piston stop locations)

That mark was at least visible with the light, so it's close. Couldn't tell you how many degrees.

I'll head back tonight and take another stab at it.
Am I going to line up the mark on the balancer with '0' or one of the other marks on the indicator?

Then what?

And without the tape, there is no way to effectively chart the advance, correct?

Gotta head out and survey the damage. They're not predicting power back till tomorrow..... Ugh

If your timing light has the advance feature, you only need to have a mark at TDC. The light will do the rest for you.

Where does your TDC mark line up with the marks on the timing cover?

Matt-
I bought the same light as you.

My TDC mark ended up being just visible at the edge of the magnetic probe socket.
