1966 ford 2000 won't start

My 1966 2000 was losing power so I decided to clean or
replace all fuel filters. The one in the fuel tank and the carb
were pretty clean but the fuel pump filter was plugged almost
completely. I opted to replace the fuel pump instead of
rebuild. I also took off the carb and soaked it in carb cleaner
for a few days as it was kind of cruddy. Put it back together
and it won"t start (it was running fine before I took it apart). It is
getting a good spark and seems to be getting gas. It fires
briefly with a shot of starting fluid but won"t run.

So I am wondering if there is a step I missed?

Does the float chamber need to be primed? Looks like there is
a drain plug at the bottom.

There is only one needle valve ( which I never touched). Is
there a standard or beginning setting?

Any other suggestions?

Thanks in advance for any advice.

Soaking in carb cleaner could loosen varnish material that is thinly deposited here and there and cause it to concentrate in a few key locations such as jets, effectively plugging them. When I have cleaned carburetors I separate top and bottom, remove jets, clean passages with a fine wire, rinse passages with carb cleaner, then reassemble with new gaskets O-rings, jets etc. from the kit. If the old float valve is solid steel and the new one is rubber tipped I reuse the old one.

I read here this carb is very hard to rebuild.. Float in particular
is finicky. So maybe I will pull out the needle valve. When I
reinstall is there a preliminary setting - like screw out 1 and a
half turns or some such?

The main jet is high speed or load and doesn't really come into play except under load. 1 and a half should be good.

Thanks. Besides this one jet are their any other adjustments besides idle speed and choke?

The float height is very important for good performance, you need to get the specification from your manual. 1/4 inch would be close enough for it to run reasonably well.
