DO NOT do any sort of business with this company. I ordered a marine quadrajet from them on 6/16/2014 didn't receive it, or any shipping info until 07/02/2014, and what I received was junk. Severely bent throttle linkage toward the carb body which caused a pinch point in the primaries not allowing them to close fully on their own. The secondary throttle shaft retaining pin was installed backwards which caused it to rest on the divorced choke housing holding the secondaries open at all times, and a vacuum leak in the secondary throttle shaft. I contacted customer service and spoke to Curtis, who fully agreed with the condition of the unit, and I told him I'd like a new unit seeing as I had paid for a product, and not received what I had paid for. He said he would send a new unit, and I would happily send back the faulty unit. He requested an email with pictures, so I sent him detailed photos via email, and after a few days of non response, I called, and reminded Curtis of our conversation, only to have him pretend he didn't know about it, and "asked the owner" who then told me to F#*K off. I spent $260 to have this company and everyone in it to treat me this way, and they feel they can charge you, but not hold up their end of the deal and stand behind their products. Now, I have to spend more money to take it to a PROFESSIONAL carb shop to have them fix the mistakes by this company. Again, DO NOT buy ANY products from this company.
