I bought a rebuilt carburetor from Carburetors and More for my boat earlier this year. At first, Chuck lived up to every other review I could find. After repeated attempts to reason with Chuck about the definition of a core, and subsequent refund, he did make good on his end of the transaction. Despite my lack of confidence in Chucks product, my new carburetor is running like a top. ChuckRosa is tough to deal with but his carburetor works wicked good. Morgan from Boston.
