I have been having trouble getting my rochester 2G carb jetted correctly. I use stock jets and drill them out. I am currently running .091 and it seems a little rich but the plugs look lean and the engine heats up to 220 in the feature. Some guys at the track told me to switch to holley jets they said that was my problem. I don't see how the holley jets would make any difference. Also where do i get a tap for the holley jets?

Take a old set of Holley jets that you KNOW you will not use. Screw them into the hole. The threads are close enough to fit and the junk jet will cut new holley threads.

the holley jet numbering system is not a thousanths-of-an-inch measurement. it is a measurement of flow.
the genuine holley jets are better than most "cheaper" brands as they are nicely radiused and flow tested ie. 2 #70 jets may not have the same size hole.
