A quick question for any mechanics - when removing the clutch on the echo power units, how does the actual clutch assembly come off from the crankshaft/flywheel? From what it looks like - it appears to be threaded on. Is this right? Is it a reverse thread or a right hand thread? Or does it come off some other way? I don't need to take it off now - however, I'm sure I will need to sometime in the future and I'd like to find out ahead of time. Thanks for the help in advance.
