Going by memory
I think it is an extra part to the enrichening circuit
only used at start up.
Many died years ago.
The heater (electric) burns out
and they get carboned up.
There are o-rings that seal to carb body that
need to be good.


ps Dont hesitate to correct me.
It's been a while

I'll try to post up an image...

EDIT: try again.

EDIT 2: sorry won't work. must be too big or something.

Anyway, it's an exploded diagram of the Solex PDSIT 34 carb. It says the piece you're interested in is a "Valve - thermo cut-off". I have one, but it rattles and I am not convinced that it's doing anything at all.

Cheers, A.

I would leave it in circuit with wire attached unless u check it for operation.If not operating
and you want to remove it the carb holes need to be modified.
It gets power from the coil +.
