I don't know that I would blame this on vacum leak though. It sounds a little funky and I would be suspicious of the carb itself.

As long as the line to your vacum modulator isn't cracked or broken then it will work no matter how much is metal or rubber. There is generally a metal line running from the engine to the trans though with a short piece of rubber line at each end.

Starting fluid didn't help.
My next move is to cap off all of the ports, on the carb and the intake, to see if it runs better...
This is some annoying crap yo'!
If I had the money, I would just take it somewhere and make somebody else find the problem.
It's pretty sad. I put all this time and effort into this motor, and now something small is pretty much defeating me... *sigh*
It's like cooking the perfect steak with all the right fixins to go with it, and then when you sit down to take a bite, your teeth fall out.

your teeth fall out.


Well it's sounds to me like a fuel delivery problem. If you're shooting starting fluid around the carb and intake didn't cause the engine to speed up momentarily then you don't have a vacum leak.

What kind of carb is it and what kit did you use to rebuild it?

[70duramax]

wow you rebuilt the carb but cant install a helicoil? weird!

[70duramax]

or know what starting fluid is? carb clean will also work or even brake clean

[70clone]

you shold fix the obvious problem first. with everything youve done you could have heli coiled the whole engine there not that expensive and they are very easy to install. i can have the carb off in 10 minutes and helicoil installed in 5.in 30 mins you could be done.

What can I say... I know what I've dealt with in the past.
I have a friend that can rebuild th350 transmissions all day, but couldn't tell me how to pull a camshaft.
It's all in what you've dealt with, and what you know. I can deal with carbs, but never even heard of helicoils until this thread.
