    Posted: 28 May 2023 at 10:19am
Hi.

I’m working on a 1948 B with a Marvel Schleber carb. It’s a TSX 154.

- Is there supposed to be a jet below/under the nozzle? There’s a jet in the bottom of the main bowl and the idle jet on the carb top. I’m seeing conflicting info on a jet below the nozzle.

Like them all, but love the "B"s.

Mine is fixed. But not like any in the diagram. It’s closest to a Type A. It does not have the Jet labeled as 26. But maybe it’s just missing?

It does have a jet where 27 is, but there is no adjustment.

I think you need a jet #26... unless you have an external adjustment #1A needle..

how does it run without jet #26, but has jet #27 , but no needle valve ?

Oddly enough it does run. It doesn’t idle though. I got an overhaul kit and took the carb apart to sort out tue idle, that’s when I realized there was no jet “26”.
