Hello there cats and kittens. I replaced my intake manifold gaskets on Saturday and now the car won't idle. It will start and run for the amount of fuel that I pump into it from the accelerator, or if I keep my foot on the gas it will stay running but it won't idle. When I took off the intake manifold I left the carburetor on top of it and turned it on its side to clean the gasket material from the bottom of the intake manifold could I have done something to the carburetor by turning it on its side?
The floats in the carburetor might have been disturbed. You might have to remove the top of the carburetor to inspect that the floats are working properly that might be your problem... check your carb linkage, hoses,etc.
Glad you thought of it and found it.
Last time I had my intake off, the car wouldn't idle after I got it all back together. In my case I noticed a vacuum leak sound and discovered that I forgot to connect the hose for the brake booster to the manifold. Hopefully yours will be an easy fix too.
If the car runs as it should when you use the gas peddle your idle adjustment is now to low after the repair
Increase you idle adjustment until you get the car to run and hold at an idle
To low idle adjustment will shut the engine down
Do check all connections and hoses for possible issues first
Turning the carb on its side should not effect the way it should be working if nothing else was done to it
I do not understand your post about the pins so explain that to me if you can
You have a leaking or stuck float, or a bad seat to the float valve. Change out the brass tube and seat since you have an old kit. The tubes and seats are matched, so dont try to cheat and just do the seat.
Shake the float to see if gas is inside a float.
you're getting fuel in the accelerator bowl, but none is coming into the jets or the idle circuit.
were the bowls full of gas when you took the top off?
if so, it's the most likely thing that when you inverted the carb, all of the dirt that's always at the bottom of an antique carb's bowl went into your jets and your idle passages and clogged them.
From Mark’s post feels like a carb rebuild is in the stars as what he is saying makes a lot of good logical sense
