ok i have a 1050 cfm dominator carb i want to try to run some e-85 in it to see how it runs heres what the carb has in it 50cc pumps front and back .040 squrters and 83 jets I am just wanting to know what size jets i should try to go up to and what size squrters i should go up to to run E-85 i know there is tons of threads on e-85 but i just want a simple answer thanks Eric

Find the diameter of the 83 jets. Multiply that by 1.47. Find out what jet that corresponds to. According to my research, that's a 95.

Ditto the squirters. .040" times 1.47, get that size squirters. Idle feed restrictors, up by 1.47.

No power valves, I assume.

Emulsion bleeds: If you have screw-in orifi (I have no clue if Dominators do), you'll have to change those. The 4150 Holley metering blocks for E85 use .028, blank (no hole), .028, blank, top to bottom. I'm not sure how that would work on a Dominator.

Idle feed restrictors not to sound dumb but what is that i prob know what it is but not sure
----------
nevermind looked them up on summit i knew what they were sorry

according to the math i need a 58 suqirter but all summit has is 50s and 70s what one should i get

according to the math above and 83 jet is .097 x 1.47 = .142 and the jet size is 142 alcohol jet is this right not sure if i did it right

Actually, I didn't state that very well. You need the diameter so you can get the flow area of the jets/squirters/restricters.

So, more like a .048-.049 squirter.

I got the jet size from an Excel file I made that used the diameter to get the flow area, then multiplied that by 1.47, calculated that diameter, and matched up what jet that was. So, that is still correct.
