There are many people rebuilding carbs all across the country and most know what they are doing. I will say that I cannot think of anyone near you who rebuilds. I say your best bet is exchanging for a rebuilt one at Berts for $225 which may be a bit more than say having someone rebuild it themselves but Berts goes through a lot of trouble.

PSA, Renner's corner says they no longer rebuild carburetors. A & L parts is another option. You xan't go wrong with them and they are in the Northeast unlike Berts which is way out in Colorado.
