I bought a new 32 36 from fast road cars via eBay. I think it was a Spanish one as there is no anti stall like the picture. It came jetted for a two litre and sorted out the poor idle and resistant pick up.i also fitted the dgas type flap operation so both chokes open the same and the kit came with a different jet to fit, can't quite remember but the top had to come off.
I also binned the choke and choke flaps along time ago. It is said a 32 36 weber is good for up to 140 bhp and ouflowsa single dcoe or dhla.
