I have two caburetors I would like to sell. The 750 has mechanical secondarys with the choke removed. A month ago I just went through it, cleaned it, Squred every thing up and put a new rebuild kit in it. It is curently on my 455. Idols good and runs exelent with no dead spots. The 950 HP is a Carb that I bought off of a board member here and he said it was pulled off a running 455. I never ran it but, when I recieved it in the mail it did smell like fresh gas was in it. I bought it for my 462 and never done anything with it because its still on the stand. My build has change there fore I will be going to E-85 next year. I have a photo of the HP but I will have to get one of the 750 in a day or two, the car is at my friends shop. $300 for the 750 $400 for the 950HP sold Thanks for reading my post John W.
