I want to replace the rubber carb cover on my sport 90 w/oil injection and have seemed to come to a point where I am seeking advice. The choke cable came off fairly easy at the handlebar, no problem there. The gas line can come off easily at the petcock, no problem there. But......when I unscrew the round throttle connector to the carb and pull it out is connected to a round insert with slot that has a metal spring inside and jet. I am assuming the throttle cable needs to come through that slot, however the spring needs to come out along with the other brass thing that goes into the round insert? Is there some procedure to make things easy to remove throttle cable from carb that I am missing here? The throttle cable is connected to the oil cable under the bike so I dont think you disconnect throttle at the handlebar as the connection is too big to go through the rubber carb cover.
