Well I posted before of how the clutch bell started rubbing the clutch after my first two tanks, I took it apart, removed the engine shim re-installed and idled a tank through it with no blades..
All seemed ok.
So today I goto the field and hover a tank through it, seemed good except the head didn't want to spool down when idling just kept spinning.
I thought it was due to my higher idle since I'm running it rich for break in.
Well on the second tank it just didn't feel right so when checking the engine temp the engine died (just from being so rich at idle) On restart I noticed some dragging of the clutch bell and metal noise again.
Sure enough the clutch bell has dropped down more and is rubbing the clutch again.
It was at this point I noticed this.
What gets me is the starter coupler is not loose, it never has become loose, I wouldn't think its the bell slipping down on the shaft as I have installed the snap ring in place of the eclip as suggested.
I'll have to tear it apart tomorrow and see, but I'm guessing once I get everythign back in place I'm gonna have to go back and re-install that shim between the fan and engine as I had it to start with.
