Carbs - rebuild or buy new

[Avenger]

Find a copy of "Rochester Carburetors" by Doug Roe. It's a comprehensive book on what it takes to do the infamous slobberjet right. They actually are good carbs when you get past the few known issues. They've mixed fuel for millions of GM vehicles and even a Ford CobraJet. If Ford is buying a GM carb for one of their high performance engines it can't be too bad.

Yeah - the Qjet is probably the most complicated standard production US carb ever made AND it had production casting plug leaks that need to be addressed in a rebuild as well.

Which is why they are known as Quadrajunk and/or Quadrabog within many automotive circles.

Right.... and Ford Variable Venturis and Jezus Chrysler Thermoquads were far simpler and more reliable.

Based on my experiences with them, with a fresh and GOOD rebuild, and proper tuning, they are fine for a couple of years...and actually work well...but not for long. That's when the Quadrabog rears it's head. The new/updated ones being sold today don't seem to have that problem. Thats coming from my days of owning 60s and 70s Impalas. YMMV

holt shit ----did you say variable venturi? what a piece of crap..... we had them on about 500 police cars in the eighties... thank god for fuel injection

I've owned my boat for 9 years with quadrajets and haven't had a bit of trouble.
