Serial E0001839. Having a few issues with this little motor. First, the little friction cylinder. The bolts are tight, but it just not keep the throttle in position. It tends to move when running and I have to hold it by hand. Second, is idle. I cannot get this motor to idle. It will start at about mid throttle and run decent. It has a brand new fuel pump, I had a friend who restores older outboards take apart and clean the carburetor. Slow needle is about 3/4 Out and high speed around 1 3/8 turns for a starting point. I have tried adjusting from there in 1/8 turn increments with no success getting it to idle. Tomorrow, I plan to test spark and compression and check all of my lines again. Is there anything else to do? Do I need to take carb apart and replace everything or am I just overlooking something. Thanks
