Hi,

The accelerator pump on a Solex PSEI carb of a Super Minx isn't working. I have changed the diaphragm & spring and blown through with an air line to ensure no blockages from pump to swan necked jet.

Any other ideas where the problem might be?

Cheers

It's likely that the accell chamber is not filling then. A carb strip and clean job to degunge the float chamber passages would be the next step IMO. If you have access to an ultrasonic cleaning bath in a local garage that would be best but copius spraying with carb cleaner and an air jet should get things flowing again.

The chamber with the accelerator pump/diaphragm does seem to fill with fuel as when you remove the cover fuel does drop out.....
