500 carbs

My wife's 500 occasionally cuts out when closing the throttle. I strongly suspect a carb problem. I believe that there's a problem on the idle circuit of the left hand carb that doesn't respond to the mixture or idle screws. I've had quite enough of taking it to bits and putting it through the ultra sonic bath, so I bought another carb. I made a mistake and bought a 32mm PHB rather than a PHF; PHB being without accelerator pump, originally a two stroke carb like the 36mm PHBs fitted to most SFCs.
So, two questions.
1: will the 500 which is very sensitive to set up work without the pumps? Any body have any experience of that? My 600 TT2 runs two 36mm PHBs and runs fine but then, it's intended for wide open throttle mostly.
2: Is any body interested in a swap between a 32mm PHB and a PHF, left hand side?

32mm PHB was the carb fitted to the Chott.

Not uncommon to have different emulsion tubes for 2- and 4-strokes, good chance the Chott carb won't work properly, no matter how you set it up. These tubes are pressed into the body and not really meant to be replaced...

Which side do you need Paul? I've got a small selection of usable carb bodies, maybe there's something in there for you. Mainly triple carbs without the slide stop, but I'll go through the stash once I know what I'm looking for, I owe you a favour anyway. ;-)

I’m not sure there is any need for pumper carbs on a stock road going Alpino. In any case, it’s my experience they often stop working - but the bike still keeps going forward when you twist the throttle.

Hi Piet,
Left hand side is needed.
