Rsk_141 Posted March 17, 2021 Share Posted March 17, 2021 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 . Quote Link to comment
TonyGee Posted March 17, 2021 Share Posted March 17, 2021 if its got both screws then yeah start at factory, you will end up screwing the air screw in and the fuel screw out. Quote Link to comment
Rsk_141 Posted March 17, 2021 Author Share Posted March 17, 2021 Brilliant Tony cheers, got the carbs off today, will try it tomorrow . . Quote Link to comment
BigT Posted March 18, 2021 Share Posted March 18, 2021 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 Quote Link to comment
