Top Quality, better than you can buy elsewhere. I buy best parts in bulk and put together myself. Best accel pumps, Ethanol Resistant. Also include new springs for under the accel pump. Gasket carb to aircleaner almost never in kits. Includes all checkballs and clips. Don't let price fool you; these are the best out there. Includes upgrade one piece needle and seats, I refer to as checkvalves. These improved valves resist sticking. Three kits for three carbs. For a nice finishing touch, I have a new set of blackened screws and washers you can add to the rebuild kit at a savings or buy seperatly on the page.
