hmm tranny fluid in the engine sounds bad. I'll have to check. I'm hoping it's the tube or for whatever reason that brass fiting is bad I'll go check. (I never thought of sucking on it haha) well brb.

yeah, usually if the modulator is bad you'll see tranny fluid on the end of the vacuum hose where its plugged into the modulator.
yeah, they are easy to change - only one bolt and they come right out. if you have to remove watch for the little rod behind it, dont loose that lil bastard. there are a couple different modulators and they are identfied by the color stripe painted on them. green or yellow come to mind.
chances are the vacuum hose just came unhooked from the modulator though, those rubber hoses get sloppy and loose after a while........ hmmm, sloppy and loose......... nevermind i'll shut up now
hell the hose itself may have become brittle and cracked, or had a hole burnt in it from the exhaust.... so many possibilities

Ok so I sucked as hard as I could on that hose and nothing. I"m thinking for some reason that brass fiting isn't the right one. Because I tasted bad hose but no fluid so that's good. I guess I'ma take a trip down to ace and see if I can't find what's right.
*edit* btw does anyone else have problems where it takes forever to load some of these pages? Or is it just me?

Looks like my next stop is the modulator. I put a better brass fiting into the intake and now it runs worse I think. It actually dies at a stop now. The hose looks brand new so I'm assuming it's that diaphram. Hoping actually because if thats not it a plug is going back into that intake...

If you have a vacuum meter, check how much vacuum you have at that port; i'm sure someone on here can tell you what your engine vacuum is supposed to be at idle.

Hmm well the reason I think it's a vacume is because when just that plug was in there the engine ran GREAT. Now that that brass fiting and hose is hooked up I'm back to running like cripe again.
But yeah that hose did seem to keep a vacume and after sucking and putting my tounge on it it kept a vacume... so I'm lost.

Did you check your intake manifold bolts? It is possible that some of them may have backed off. (I mention this because you just installed it)
If they backed off you could very well have a vac leak. This would be unlikely, but possible. While you are at it make sure that the carb is snug against the manifold too.
If this is good, start with the ABCs of engine diagnostics, which is really not the ABCs but IFT
Ignition Fuel Timing

Well I had a torque wrench I actually used to put them on to 20 lb ft torque. so I doubt but I could check it. Carb is brand new and installed at the same time and I can check it again. And my distributor is brand new as well lol and I know that thing got hooked up right. We also timed it and adjusted the carb too so.
The thing is I bet that if I do put that plug in and start it (not drive it lol) the engine will run strong again.

maybe having another source sucking off the vacuum has changed how much is sucking on the dizzy throwing off the timing? thats a biggggg shot in the dark. if you wanna be sure about vac leaks on the intake gasket spray some carb cleaner along where the intake meets the heads. if the engine responds to it something is leaking.

What I am going to say is not a huge time saver, but you could achieve the same end by simply removing the hose and pluging the end of the fitting. You could do this by simply cutting a piece of hose and sticking a bolt in one end, asnd putting the other end on the fitting.
Also, how old is the engine in your car? If it is orig. you might have a timing gear issue. They were nylon coated, and they usually always fail at about 100,000 to 130,000 miles. If the chain slipped a link, the motor would run like crap, it would be hard starting and it would bog down somthing fierce.
If the motor has been rebuilt in the last 10 years or so, you probably wont have a nylon gear, and this almost certainly will not be an issue. It probably isint an issue anyway, but I an grasping at straws.
This can be checked by putting a timing light on to see if the timing has vastly changed since you last timed the ignition.

They nylon gear was something I was going to check but that'll be the last really. When we opened it up it looks like someone completly rebuilt that engine. Clean as a whislte. It's not the original engine I believe it's actually a 302 in it now. oh and we replaced all the gaskets when we were in there too. intake + valve. I'ma play with the dist. and see what I get.

+1 on the distrubutor turning,,,,, BUT,
I advise that you put the timing light on and check the timing before moving the distributor, this will provide you with a little bit of diagnostic information. You will be able to tell if the timing has changed since you put the manifold on. If the hold down is tight, the distributor probably has not moved so if the timing is quite a bit different, the logical place to turn is to the timing gears. I would not mess with the gears if the timing light shows your timing has not changed. If the timing is the same you can rule out the timing chain as the problem.
Once you move the distributor, you no longer have a benchmark to determine if the cam (and therefore ignition) timing has changed, and you will not be able to use this "tool".

Forgive me for my ignorance but is the timing light a tool I need to go buy or something else? I've never used one and didn't use one before or after we put the intake on?
