Carburetor Adjustment on 1978 Johnson 55 2-CYL

[vaughneric2000]

I have a 2 Cyl 1978 55hp Johnson. I have rebuilt carbs, and motor now runs much better after sitting all winter.<br /><br />It idles very badly; however, there are no adjustment screws on my carburetors at all. Do these carburetors have needle valves (other than the float needle--that assembly came in the kit)or a way of adjusting the jets?<br /><br />Thanks,<br />Eric
