2F Engine Tunning Question

[Razor]

My 77 FJ40 Starts perfect..Idles perfect, however...when I come to a stop it will die sometimes and want to stall when getting going from a start...you know blug blug blug....feather clutch and go.

I haveto have the choke pulled out a little to keep the R's up.

Is there one thing that I can pinpoint and fix.

Only thing I have done to it is....
-new plugs
-new air filter
-new fuel filter

I don't mind the issue, but my wife likes to drive it and has a hard time when it stalls at traffic lights.

Truck has 41K on it.

thx,
R.

Razor,

I am no carb expert, but it sounds like carb trouble! Vacuum leak or other.
I have a '78 and one time I got some water under the hood. Messed up my voltage regulator. Also, I had to run w/ the choke out to keep her from dying at lights. Turned out the fuse for "engine" was blown.
Do you have said fuse?

I would check out the timing. Vacuum? A vacuum gauge should help you with both fine tuning and diagnosis of your issue. Indeed you may have a vacuum leak, but other issues could be playing a role as well.

It might sound like a shot in the dark but check your PCV valve.
