rochester feed tubes

I am trying to rebuild a Q-jet and it look like the last guy in crushed one of the fuel feed tubes. Anyone know were I can get new feed tubes? the carb is a rochester Q-jet #17085227 0646 HLZ I don't know what it came off of?

Get any old junkyard QJet and swipe them. I assume you're talking about the tubes in the air horn casting back by the secondary bores. Same tubes from any QJet will work. Be careful getting them out of the old carb- they don't come out easy unless you get lucky. I have gotten in the habit of lock-titeing them in place when I install them so they don't vibrate back out. once they've been in and out a few times they get a little loose.

best i can due at my local junk yard is $30 for a used carb. I was hoping they were a 5-10 dollar item new. but you got to do what you got to do.

Chuck- if you have a local swap meet or flea market you can get a whole box full of junked QJets for about $10. Swipe what you need and resell them to the next guy for the same $10.

While you got them out might consider drilling 4 small holes through the center of the emulsion tubes about the size of a pen tip. This trick helps transistion into the secondaries better. This is basicly the only internal modification so what the hay.

I have seen this mod before. does this allow some gas in sooner to reduce the bog when you punch it?

In a sence yes. It allows fuel to pass quicker and smoother so if the secondary tesion, rods and hangers are all perfect it completes the rest of the equation.
