r/carburetors

I took this carburetor off my 1969 international 1100d. I thinks it’s a 1904 Holley carburetor. I know there are differences between internationals and amcs and fords. It’s an international 240 inline 6. I was hopping to find out exactly what this carb is and what rebuild kit to buy. Thanks a lot.

If any more information or pictures is needed please let me know.

Trying to find where this linkage goes on a quadrajet for an 82 GMC. I found it sitting on the engine and I'm not sure if it goes next to the other linkage on there or somewhere else.

What would cause this? I figure it’s the carb, just wondering what could be plugged/broken etc. I’ve had the carb open, however I haven’t gone too deep, I’m just trying to get it running ok for as cheap as possible.

Thanks in advance!

I’m working on a carburetor for the first time in my life, so I am at the bottom of the learning curve.

It’s a Holley 4150 series, 750cfm four barrel double pumper which sits atop a 454 in my ‘72 c10.

The truck is running rich, fouling plugs, so the first thing I want to do is clean and rebuild the carb with fresh gaskets and whatnot.

I’ve gotten as far as taking it apart, but I for the life of me cannot get the needle and seats out of both fuel bowls. They appear to have been screwed down too tight into the bowls, with the flats on either side flush with/below the casting level of the fuel bowls (yes the nut & gasket is off).

I bought the Holley rebuild kit (37-485) so would rather put the new ones in there.

How can I get them out?

I have attached two photos: the first one shows the primary bowl from above where you can see how flush the needle & seat is with the casting.

The second photo shows inside the fuel bowl – by unscrewing the little cover over the float hinge I can get to it from the inside. Is this my best option?

Thank you in advance everyone; I appreciate the learning!

Bought this used one( its very dirty yes im gonna clean it professionally) but it makes some scratching noices when i open it. I think its because of sand on the rolls and i think it will go away after cleaning what u guys think? I think the inside doesnt look worn off but im not a Professional

Thanks!

My truck, an 86 c10, has a new to me QFT 650 electric choke on top of a sbc 350, the qft runs great other than coming off idle (like leaving a stop sign) it stubles and kinda dies, it does even out and continues running like it should, any idea what could be the issue. Sorry I dont have a pic of the carburetor

I cannot for the life of

Me find this manual for this carb anywhere. I can’t even seem to find another similiar. I seem to remember them being 650’s.

They are vacuum secondaries, single fuel inlet and from what I understand this port is for a boost reference.

The carbs work great and this thing is a handful but I would really like to find a manual for these…..

Thanks

I for some god awful reason chose a AVS2 over a 1401 or a holley and I dont know if my secondary’s are even opening because when I go WOT it bogs down horribly it makes a deep grumble sound like the throttle plates open and are letting some air and fuel in but I stay put any advice?
