I know how you feel about losing your favorite tool. Mine is my picket screwdriver. I use it in every car I work on!
Great tutorial. I like quadrajets.
Thank you
What jetting, primary and secondary’s do I need for my 87 caprice classic quadrajet for here in TX? Was rebuilt and jetted for Colorado altitude so I need to change that. Any and all advice will be extremely appreciated
hello my engine builder swapped out my jets not sure the size as the number is all messed up on the top, it had 73 jets, but he did not use the main metering rods what effect will this have ,, i just put the original stuff back to try the difference since the motor has been rebuilt as a starting point
Did this carburetor have the original parts? What type of engine is it usually mounted on? Would it work for an omc cobra 5.0 v8 engine? Can you tell me where I can get the paper you use in some of your videos where the quadrajet models come from to know their jet and primary needle specifications? all the best
Is it important to have that plastic cover over the float? My 17058213 carb doesn’t have it
Yes, the float cover is needed.
What would be the purpose of changing the jets in the carburetor? How would you know if they needed to be changed?
Each carb code was calibrated for a specific application and fuels back then. If engine is changed, or carb moved to different than original engine, it needs to be calibrated and jets are one step to that.
Also, with todays fuels, a stock carb can use a size larger in jets than original to allow more fuel.
@@QuadrajetPowerLLC Thank you for responding.
is there a way of getting better mpg by changing the jets and primary rods?
It’s not quite that simple. It’s more about optimizing your engine and once it’s running correctly your mpg’s will be as good as they can get. That being said: quadrajets are pretty much the most efficient 4 barrel carb.
Hey guys I have a early 66 quadrajet on a 327 and the bowl has a Preston needle and seat I need to thread it because it leaks is there a tap for that
The early seat uses the o ring fitting with 2 screws holding it in place. It will not accept the threaded type seat. We sell the type you need.

15:40 I've ordered 3 rebuild kits from you and they've never came with a power piston retainer
I looked up your name and don’t see any orders from you. You must be ordering from somewhere else. All of our rebuild kits include power piston retainer. Order your kits from us next time. We would appreciate your business.
Fuel injection will never atomize the air/fuel mixture.
