Got a new Diablo the other day was working fine for a few hours then the drive shaft would stick when i went to run it i would have to give it a shift with my finger and it ran but every time i stopped to restart it would stick i thought it may be the ttec needle bar making it jam so i switched to normal tip and needle same problem today running a liner once its in motion its fine but it is annoying when it jams you can hear the motor trying to turn but drive bar sticks i was thinking of giving it some lube but being brand new it shouldn't need any grease just yet any suggestions
