Re: Max Jets and pin guages
Holley jets are rated by cc's per minute flow in volume. If you have access to a flow bench it is very easy to match the required jet to the dry air flow of the carburetor, then from there it all becomes a function of the atomization circuit and the fuel curve.
On the question of the pin gauge diameter: Example a .010 diameter: Minus = .009 plus = .011 |

Re: Max Jets and pin guages
A good guage pin set will run like this
minus .010 pin = .0097-.0099 plus .010 pin = .0100-.0102 Try MSC, McMaster Carr or Grainger. MSC is you best bet, they are the Walmart of industrial tool supplies. Most sets run from .011-.060 and then .061-.250. The bigger sets can get pretty expensive. Another way is to use the shanks of the drills in a number drill set. You don't have every .001 increment but you can get an idea of the hole size. They run from #60 (.040) up to a #1 (.228 I think). |
