Gs 550 carb Adj

[Rsk_141]

Got some Gs 550 vm carbs running k&n and after market 4into1 swapped out jets book tells me air screw should be 2 turns out as a start point .

It also states Fuel screw is set at factory and shouldn't be moved, "well that ship has sailed"

I was thinking 2 turns out as well any advise would be great .

if its got both screws then yeah start at factory,  you will end up screwing the air screw in and the fuel screw out.

With pods and 4-1, set the fuel screw one turn out from lightly seated and the air screw around 2 turns

Tune the idle with the air screw

Fresh O rings are very helpful
