The only jet adjustment is the idle jet and that will be on just the top 2 carburetors. They are set at 1.5 turns from lightly seated. You will need to check the trigger when you advance the throttle be sure it is moving freely. When you advance the throttle it should move at the same rate as the throttle arm. If the trigger is sticking it will cause a lag or bog when throttling up. So check the linkage closely for free movement and the idle jets for correct adjustment. I will need the engine serial number to be more specific.
