Repairing this for an elderly neighbour
Engine ran, head wouldn't turn - pull it down, one of the clutch shoes had disintegrated.
Install new clutch assembly, put it all back together, Runs fine for a few seconds then head stops turning (speedfeed). Take the SF head off and everything is fine again but when I screw it on, it screws everything up tight and won't budge....what am I missing here/doing wrong? Is there a bit missing? I've never used a speedfeed head....and this is doing MY head in
