Working on my buddies blaster, I convinced him to go premix and ditch the oil pump set up. This is on an 04 BTW. So what I did was undo the pump cover, undo the two screws and pull the pump off the shaft coming out of the engine. I then took the four screws out and pulled the internals out. Lastly I pulled off the metal gear in there. Is that the right gear I read about to pull out? Also, the line that goes into the carb, how is that fixated? Its got the gold colored ring around the end. Thanks for any info and insight.
