Work with the carbs first, and then worry about the pump.
Warm up your engine, set the idle. Adjust your throttle cable so that it does not have too much play. (I don't have the proper procedure for that- maybe your manual indiactes something.)
If you are going to sync your carbs this is a good time to do that.
After all that, check your oil pump. There will be a moveable lever arm that the cable attaches to. Near the pivot point of the arm will be an index mark (line or dot). Also, on the body of the pump will be another index mark. You will need to lign these marks up at either idle (or full throttle - depending no your application). If they are not ligned up at either idle or full throttle, you will need to adjust the cable to make it lign up. Adjust the cale going to the oil pump - there should be some jam nuts.
Good luck. -Jace-
