Brought a used weber 32/36 dgv and have rebuilt, rejetted and put in appropriate emulsion tubes for my 1300 Kent xflow but the bugger won't start. I've noticed the diaphragm for the power system is also stuck in and won't return outward for some reason. I'm sure another strip down and rebuild would rectify it but I'm keen to know what else is out there that would fit and work (maybe better) for this? Anyone use any other carbs?
