Could I just put a vacuum line with a smaller diameter instead?

For what its worth take the whole thing apart and clean all the carbon out. Its comes apart in a few pieces.

Not so lucky,

Here is one way,


pick a washer with a smaller hole....

and stake it in place.



If your NOx readings are very low, i would just cut out a gasket without any holes in it and mount the EGR valve. it would pass visual that way but not work. The gasket will not last forever though.

or put a plug inside the vacuum line so no vacuum would reach the EGR.


OR

as 86... mentions. Just clean it. It might not be seating properly causing a leak at idle.

Is there a reason that I just couldn't limit the vacuum with a smaller diameter line?

Smaller line still gives the same vac. just a bit slower is all to load.

If I remember correctly that EGR valve comes apart in two or three pieces. I really think the different sections just thread together.

I disconnected the egr from the cto and plugged it and now its still almost stalling. It doesnt happen when I rev it up only when i give it some gas to start from a stop.
The engines running perfectly smooth, I messed around with the floats, the timing, the egr. Nothing is helping the problem?

The EGR could of been full of carbon and once you started to make it work again, some of that carbon build up could of come loose and is now keeping it open all the time.

It feels like its closed all the way, I dont want to pay 80 bucks to get a new one and I cant seem to get it apart without bending the edge open.

If i depress the diaphragm and plug the vacuum port with my finger it slowly returns to the closed position. Does that mean its bad?

Good question. I'm not sure. off hand I would say there is a leak someplace. Some of those hold vacuum forever.


The real problem is if the part that seals off the intake is clean and not leaking.

If you have some gasket sheets, you can cut it to block off the EGR as a test. NAPA sells gasket sheets. Get a thick one.

Hey guys I PASSED! I had to adjust the pump travel and the metering rods to get it to not flood. But I passed!
Thank you all so so much! You guys have all helped very much!

Soon im going to start a bild/restoration thread for my Jeep where ill be asking questions about paint, dash board guages (John Strenk ), etc. Ill also be posting pictures of my progress.


Quick question, iv noticed that the only way i can keep the engine from flooding is to have the choke pulled out a little bit. Is it normal for the carb to like the choke closed off a bit? or do i need to re tune it again, if so what do i need to adjust?
