Hello all, it's too bad my first post had to be under these circumstances
but anyway:I had some carb issues (bogging/dying that I related to the accel pump) and bought a NAPA rebuild kit for a Holley 1920. This is the carb I surmised that I had, since it says 'Holley' on it and my Haynes shows the Holley 1920 as the closest looking to what I have.
Anyway, I started out dismantling and bagging and tagging every part according to this exploded view. My carb didn't actually look like this, but I figured that was just a product of the disclaimer at the top of the page. So after getting it dismantled and cleaned, I set out replacing the parts provided in the kit:
1x pump diaphragm assembly (#25)
1x economizer diaphragm assembly (#32)
1x economizer diaphragm gasket (#33)
1x fuel bowl gasket (#19)
1x needle and seat assembly (#13) (the needle is free-moving though, not enclosed in the seat like the original)
1x needle seat gasket (#14) (the original didn't have the gasket on it, but I used it this time)
1x float lever retainer (#20)
1x pump lever retainer (#5)
1x thick manifold-to-carb gasket (#37) (but mine's thicker?)
1x thin manifold-to-carb gasket (#38 ) (again, thicker than the one pictured
and then these extra parts:
The one in the foreground on the right is a small ball bearing in a cork gasket. Very small. Wasn't on the exploded view, dunno where they go.
I got everything back together anyhow, and setup the float and fast idle to their specs. But the float spring is awful, and makes the float droop. But I had to reuse it, there wasn't a replacement in the kit.
Anyway, I started with just the thick gasket on the manifold. Who'da thunk, my manual doesn't say whether the 225 has crankcase ventilation or not. I went to start it, and it turned over but wouldn't fire. Additionally, after I let off of the throttle, it started leaking out the yellow button pictured here:
Then I added the second gasket (it has the same hole where the first one does, I don't see how it'd help). Tried it again, and had the same effect. leaking after the throttle was let off.
So I don't know what I did wrong. There were a lot of parts on this exploded view that I didn't find in mine or were set up differently.
Now I'm stuck with a leaking, non-starting carb. This is my first carb rebuild ever and I would appreciate any advice. Thanks for the help in advance.
I should also mention that it had not leaked from the yellow button prior to my rebuilding it.
edit: I searched "Holley 1920 leak" and couldn't find anything that resembled my issue
