I finally saw what my problem was with the throttle and the idle. I had took apart the carburator and didn't double-check to make sure everything was seated correctly before putting it all back together. All fixed now and everything runs good. I rode my cruiser about 10 miles today and it was great! One thing I noticed is that the motor will idle a bit when I release the throttle and then shut off when the clutch is disengaged as I'm at a traffic signal waiting to cross. I noticed some screeching and squeeling in the motor as well. Is this normal for the break in period or is this something I should be concerned about? Is there a way to remedy this? Thanks for your help.
