Gallery of carburetor rebuild pictures with some tips and observations scattered about…
Cool nozzle retainer on this Holley 4180C (Ford) carburetor (List 50264-1) but can you see that the nozzle itself was installed upside down?! That little hole should be pointing downward. Oh boy, that’s not good. #holleycarbs
This is a brand new Edelbrock 1901 with a gnarly secondary booster. They are great to work with and an exchange is being processed. But this is a great reminder to inspect everything – even if brand-new! Details matter.
Before & After of a Stromberg WW 272 carburetor. These have great throttle response and tip-in! Solid replacement for most one-barrel carbs and up to about 200HP.
You can’t make this stuff up – that’s weed stuck in the vent on this Holley 6299 carb!
Look at the differences of the inside bevel… On the left is a genuine Holley jet – the right is aftermarket crap. I only use original equipment (OE) jets on all carburetor renew projects.
The brown gasket is the old style from a never-opened kit. And while it looks great (amazingly so) these gaskets are a pain to remove. So… I am matching this old one with its modern non-stick replacement to make life easier – for everyone. Details matter…
When installing the Holley carburetor whistle-style vent baffle, be sure to install with the step facing up – otherwise you’ll be doing the job twice due to a poor fit. BTW, use this style only with center-hung floats and the flat-style for side-hung (pictured somewhere in this gallery).
Stromberg WW 2-barrel carburetor
A Stromberg WW 272 carburetor recently overhauled & sold – these are awesome!
Holley model 1920 1-barrel carburetor
Vent tube on your Holley carburetor look like this? It’s an easy fix with an easy-out. Use the easy-out to install the new vent too – but be careful not to crack the mounting area.
Look for this gasket when removing your choke on a Holley! If you see it – note it, and make sure to replace it with a fresh one. Forgetting this little detail will result in a vacuum leak that you will not be able to see when everything is installed, and it will drive you nuts – but not likely anywhere else. Details matter.
This shows the correct gasket – but it was installed wrong. The gasket tab on the lower left, should have aligned with the casting tab at the top right. Slow down and read your parts, details matter!
Broken carburetor air cleaner studs are common – and repairable. Just do not put too much effort into it or you can cause more troubles than you already have… Finesse and plenty of penetrating oil goes a long way towards a successful repair. Here’s one I did on a Holley 4412-3 carburetor.
Installing vent tubes on a Holley carburetor. Looks super easy, but be careful not to crack the mounting boss!
Look at how dry these gaskets are! They literally just fell off the metering plate. This is not from not running your car over the winter but from long-term storage – or neglect (like sitting on a shop floor for a decade). It happens.
So… that’ a soda can tab from the 70s sitting in the bore of this Holley 2818 carburetor. You can’t make this stuff up! BTW, there were actually two of these in the carb!!
DD screws holding down this Holley 2818 accelerator pump cover – now that’s old!
See the recess on this Holley carburetor vacuum secondary housing? It needs a gasket!! This one was missing. Details matter!
A bunch of big pieces, a bag of little pieces, and coffee – let’s see how this goes! Sunday Carbs & Coffee – bring it on!
This is a Holley 4160 List 8007 390CFM carburetor with a secondary metering block conversion – in case you were wondering (you know you were).
Removing the throttle blades or shaft is a last resort tactic for any repair – but if you do remove them, using a needle-nose Vise-Grip plier to restake them, gets the job done. Just make sure you can visually see the crimp. or align it up again, and try a little harder this time big fella (or lassie). *This is not an endorsement for #visegrip, but if you happen to read this – you’re welcome 🙂
Details of the idle mixture screw on a Carter WCD 2-barrel. How cool is that!
Offenhauser’s carburetor mount for the Slant-6 5270 intake manifold is super-sized way larger than what’s needed for street use. The larger size will drop pressure and velocity just past the throttle base. This part sucks – so have one made to match your throttle bores instead – it will cost about the same and provide a bit of torque to boot! Shame on Offy for not getting this right after nearly 60-years. Pictured is a Holey 6299 390 CFM carb, but anything less than 800 CFM swims in it.
Recently completed Carter WCD 2-barrel carburetor. Such a cool carb!
Almost complete with this Edelbrock AFB carburetor rebuild. These are set-it and forget-it carbs that rarely need adjustments once dialed in. Love them so much, I have the 1901 AVS2 on my Barracuda.
Brass/Bronze boosters – sweet!
Comparing two Holley 390 CFM carburetors, the 6299 vs the 8007. No clear winner, but the 8007 pictured is equipped with a secondary metering block. Sweet!
Everyone has their trick to remove a stuck power valve on a Holley carburetor – while not pretty, a long-bar gets the job done. Just be certain to add plenty of penetrant beforehand.
Looking at the business end of Carter’s WCD carburetor – such an awesome little carb!
What a mess – it’s hard to believe this turned out beautiful. Look around for the after pic, it’s here somewhere…
Yes – it is possible to economically repair a carburetor vent tube boss if it’s been broken. Even in this case, where I didn’t have the missing part. The repair came out clean, but it is impossible not invisible. It is what it is – but it works!
Check out these brass strip-metal fuel baffles. They are as delicate as they look – and boy are they cool! These were on the Holley 2818 carburetor for a 1964 Corvette with the 327 CID HP engine. Neet stuff…
Check out this brass vent baffle – replacement ones are now made of an ethanol resistant polymer and work just as good, but there’s something cool about the old brass strip-metal stuff! #itsonlyoriginalonce
Putting the finishing touches on this Rochester Quadrajet 17085216 carburetor before putting it up for sale. Nothing is I do is media-blasted – everything is fluid-cleaned to keep its well-earned patina.
