Hi,

Got both my solex 32-34 PDSIT carbs rebuilt and fixed a few small issues but what is this part and what does it do? There is one on each carb at the rear and after cleaning a can blow through one with ease, but the other is air tight (the one on the main carb)... which one is correct, assuming the one i can blow through? Soaking again in carb cleaner overnight but will this cause problems? Aircooled CJ 2000l BTW.

Any help appreciated

It is a thermostatic valve for the displacement of the accelerator pump. The valve should be closed below 19 deg C and open above 25 deg C.

Thanks bigherb

Just put the shut one in v hot water and its still shut (almost burnt my lips so its above 25º), although its only been around 20º or so here and the other one is open? Maybe they are both shot?

Would it cause any issues either way?

I'll speak to Gower & lee tomorrow to see if they do replacements?

It injects double the amount of fuel when the valve is closed so increased fuel consumption especially in stop start traffic.

So if i have what seams to feel like over fuelling on Motorway driving could this cause it, looks like i have opposites on each side, one open one shut

sounds like i need to source replacements either way?
