I purchased a Dambest billet 4500 carburetor and noticed the boosters are only epoxied in place, they are not supported as in a traditional holley and secured with stake pins. I thought they were at least swedged. The carb came with two different jet sizes in the primary side (so much for his accurate wet bench). To make matters worse, the linkage was binding. The secondary linkage would not close properly after the burnout. After close examination, I could see the throttle arms were not welded perpendicular to the throttle shafts ( he makes his own linkage). When I contacted this company on the issues I found, he was very confrontational and hung up on me. Once the linkage issue was fixed ( I purchased an external linkage kit from blp), the carb always ran a tenth slower than my old 8896. Be very careful when dealing with this company, the service after the sale, is non-existent. Go to the website, and read about the returns policy.. 50% of the purchase price is intellectual property.. For the amount of money I paid for this carburetor, I expected quality.
Buyer beware.
