I know I saw this here somewhere but does anyone have any part numbers for the rebuild kits that have the diaphragm for nitro in them? thanks.

It is my understanding that the K20 WAT kit fits the WA and WT series carbs and has the best diaphragms available for fuels containing alcohol. That is what I use in my Walbro carbs to help keep this wonderful alky laced fuel they sell here in Houston from attacking my diaphragms and drying them out making them stiff and unuseable.
