i'm planning to disassemble the carbs and give them a thorough cleaning. has anyone come across a rebuild kit which would provide replacement o-rings/gaskets/diaphrams/etc or do i have to buy all that stuff separately? i've checked out the microfiche at ronayers.com... just not really sure all the stuff i should buy. ron ayers takes a while to ship things... i'd prefer to have all the necessary parts before i start ripping these apart. thanks.
