Im curious to know what size jet I should be running in my Flathead on menthanol fuel.
Here's a spreadsheet of jet sizes starting at .044". This gives you the jet size, jet diameter, jet area, percent increase from the 1st jet, and the percentage difference between each jet and and the previous jet. Maybe it'll help you. It does give you a good idea of how much flow difference there is between the 1st and the 2nd, or the 1st and the 4th jet.View attachment 6473
