fuel distributor hose question

Where does bigger rubber line attach to ? 77 930

That big rubber line with the zip-tie (whoa!) feeds your cold start injector.

Good eye, those zip ties are not doing anything. Threw them on when i thought they were vacuum lines that slip off. Now I now they are high pressure. I figured out the bigger line goes to the fuel filter. Pretty easy to mix it up and attach to the fuel accumulator. Ask me how i know.

What happened to the 3mm CO adjustment stalk?

1977 don't have those.

Are you sure about that?

There is a hole in the air flow meter housing where it would go and a mark on the side of the fuel head where it may have been.

Maybe someone else with a 77 930 can chime in.

The fuel head does not have a adjustment stalk like the later heads. The adjustment screw sits below the the surface inside. Its a real pain to adjust CO. It looks like you are missing the cap head screw and seal the goes in the hole. Without it you'll get get a vacumm leak and a lean condition.

[dhg1337]

WOW, did not realize there was a cap for that hole. I can't find the part number for that from looking at the parts diagram. It may be part of the body. Maybe thats why there is no part number for it. I guess i could put a rubber plug in it ?

I have a 77 and my AF adjustment hole is threaded it uses a metric allen head screw

thanks again, dropped the idle down 150 RPM's once covered., one less vacuum leak.
