All,
My friend and I are working on his 87, Carbed longbed pickup, with 22r engine.
We re did the head, truck is able to idle, but still needs some work. We didn't put the small spacer when we installed the fuel pump, we will get that straight.

As for the sight glass on the carb, my friend says that it is completely full.

What are the symptoms of a carb that is full of gas, like ours with a sight glass full of gas?

Please let me know.

Thanks,

adjust the float

It'll run rich, probably 'after-run'... aka "diesel" when you turn it off. May backfire through the carb when you step on the pedal quickly... give you fits on cold starts.

The spacer between the cam and fuel pump 'lobe' / 'eccentric' isn't needed on a 22R engine. Is that what you're talking about? 22RE's have a 'spacer' or shim on the end of the cam between the cam sprocket and the distributor gear but 22R's don't but have the lobe instead.
Or are you talking about the shim on the fuel pump gasket between the fuel pump and the head?

spacing the fuel pump off from the head causes the fuel pump to pump less fuel per revolution so... that may or may not be your problem...
... IF the float is adjusted properly.

Yes,
I'm talking about the spacer when mounting the fuel pump. We are going to pull the pump, and then reinstall it with two gaskets and the spacer sandwiched in between.

We will try this first, and see if this does anything to the carb sight glass.

Thanks,

Overall, it shouldn't do much to the sight glass / fuel level unless the float is saturated and needs replaced, then you're just restricting fuel that the carburetor may need when you shim the pump out.

Get what I mean?

Try adjusting the float to limit the fuel level in the float bowl first... unless you happen to have a fuel pressure gauge there... do you?
You want fuel pressure at the needle valve, but not too much fuel pressure that causes the float / needle to unseat.
