Rebuild Kit Price?

[92Frankenstein]

I have searched for about an hour now, and I cant find anything online!

Does anyone know a price and good place to buy a rebuild kit for this 600CFM Carb.?

Also, if anyone knows how much the kit is to convert it to double pumper, that would be great as well!

Thanks to all.
