I refuted alot of the unsubstantiated BS over on CF. I am about to get flamed for doing so. Which is why it has been so long since I used CF that I had to make a new account as I forgot my pass and the email address used was one I abandoned years ago.

Lars is extremely knowledgeable about Q-jets, and is understandably biased towards them. A Q-jet is an outstanding carburetor when properly set up, adjusted and maintained! That's the secret and the headache of Q-jets today. There just aren't that many techs around that know them anymore...Holleys, Edelbrocks and Demons? Sure...lots of techs familiar with them as that's where todays carburetor market is...not Q-jets. Lars is one of those few guys that can make a Q-jet "sing".
There's also a shortage of quality Q-jet cores that can be rebuilt properly to get the most out of them. That's simply a fact or life and the good cores are in demand by Corvette restorers interested in the numbers and date codings.
I'm not going to trash the guys on CF...lots of good guys there, plus some guys that one would think are Porsches owners from their attitude. Just a fact of life. Lots of differing opinions and experiences...and not all are rooted in reality.
With the Edelbrock Performer intake and Edelbrock carburetor, I can't see how you'll be unhappy...quality stuff, easy to adjust and hold the adjustments, simple to deal with. You may well have to dial things in once installed, but you'll be happy with the results.
Nothing worth while comes easy...shedding a little blood and grief is par for the course.

I saw your post(s) on CF. You definitely heated things up. That happens over there if you refute their opinions.
Since I came across that burnt hose, I decided to put everything back, replacing the hose. (Also, had to replace the cap that I just replaced in Mystic, cause a plug wire terminal was broken. I'm guessing it broke when I pulled the wire off, but can't be sure.)
It fired right up, high idled very nicely, kicked itself down nicely, curb idled nicely, and ran around the block a couple times really well! I can't believe what a difference once little hose can make! The next test will be actually taking it out on a drive somewhere for real, not just a run around the block.
Also, I have to see if I can fix that exhaust rattle we discovered in mystic. I have to take it for inspection soon, to the guy that installed the exhaust, so I'll see if they can find it and fix it.
Looks like I'm sending the Edelbrock parts back to Jegs. I guess I'll have to eat the shipping cost both ways. Oh well.
hopefully that vacuum hose was the main source of your problem. a vac leak is a big deal.
shipping is better than paying for everything.
as for CF.. like I said.. if you disagree with lars or one of his many parrots you get flamed and that is why I dont go over there. If the point iof the c3 forum there is having one guy share his opinion and a hundred people regurgitate it then they have suceeeded.

I hit the wrong switch and it went off in my hands..It was a few comments on replacing my Q-Jet with Edelbrock carb.
I resorted to sending message directly to Adam and he may possibly send it to this forum.
In short I have substituted many Q-Jets to Edelbrocks with a great deal of success and increased the performance/operation of the engines,however the gas mileage differs quite a bit and should be considered as the Eddy's are not what you would call an asset as far as MPG as the Q-Jets...The small primaries of the Q-Jet help the mileage as long as you don't go into and stay in the secondaries,the go fast mode.....
Again, I apologize for my ineptness on the computer..

Dang...I been missin this thread for a while. Glad ya got the vac. leak fixed there, Boss. And...to Ben...yer such a troublemaker!!! I just now went to CF and read thru Adam's thread.... Now ya know why I love this place so much! Everyone's opinion/facts are accepted, and you can either take the advice/info, or not...up to you. No "I know everything about everything because I read it on the internet" attitudes here. I have often stated that some procedures work well for me, but not might for someone else. That's just the way it is. Sorry for the "off topic" garbage....I'm done now.
I hope the vac advance lines cures your engine problem, Adam. I bet it does, and your fule mileage should also improve. Adams' Apple2010-04-08 07:07:42

All I need is time and money! Getting there!
I know I haven't been on much. But I support the q-jet, which now seems to be working.
A carb is often blamed when a car does not run correctly, and there are other problems present. I am really interested in knowing how the car runs after a bit of an extended drive. I have a vested interest in this one. I was the third rebuilder. Adam sent the carb to me in a box. I rebuilt it, but do not have a flow bench. He put it back on, and it was better. Some time after that, Adam and I got together here in Ohio, and I made many adjustments. It sat over night to confirm the choke operation. Back to PA he went. It was a nice visit, but very short.
I did not have a chance to do a full engine analysis. At that time, the hose was okay. But that's been a couple of years.
Adam, before repacement, make sure all the other things on the engine are connected and working properly. And there are many, all of which can cause problems. As you now know, the little things make a huge difference. I hope this remains just minor things.
Before taking a big plunge, give me a call. Maybe I can help.
Adam you made the right decision in keeping your Qjet. I am feeding a 406 small block with one and it dyno'd at over 450 hp. When properly set up they will run with the best of the performance carbs and get better mpg when your little pedal is just caressed rather than being slammed against the carpet. The model you have can be easily converted to an electric choke by replacing the cover with an electric unit and plugging the heat tube line with a rubber plug. The power will need to be a new line from an ignition on source, but do not use the distributor feed.
Primary and secondary metering rods, primary jets can be changed to tweak the carb for performance. The biggest mistake made is in the setting of the secondary air flap. Since it also controls the depths of the rods in the jets allowing it open to soon will make it bog. this is easy to adjust with an allen wrench and screwdriver.
