I am getting this car ready to crank after a 10 year storage. The in side of the 4 jet rochester is clean, but i am going to replace accel pump and gaskets. I noticed during tear down that primary jets had a 48 stamped on one and 49 stamped on the other. Same was true for secondary. I could see clearly that the holes in the jets were different diameters. I'm thinking they should be the same size, does anyone know what they should be, or where i can get that info? Thanks Ron

After a closer look, it seems one of the jets numbering may have been stamped backwards. One is 84 84, the other is 48 84. I will try to post a picture. SO I COULD HAVE A PAIR OF 84'S AND A PAIR OF 49'S.

If that is the case , then it sounds about right .
