hey guys,
i picked up this makita rst 250 line trimmer a wile ago, and after striping it down three times,cleaning the spark arestor, putting a kit through the carby then banging my head against the wall "all the normal stuff" cause it was still a no go untill i was reading another post on this forum, that some times line trimmers can sheer flywheel keys so i thought it was worth another go and surely anough there it was, the flywheel was more than 140 degrees out of TDC then looking at the setup, the clucth sits in the middle of the flywheel or magnito i should say and it drives a small outer hub that sits in the front of the plastic cover , obviously all that load driveing the gears and bump head is put on the magneto/flywheel and that skinny little key that tore throug the soft alloy, im not sure how other trimmers are setup but i thought this was not a very good design and costing around $300 new i expected a bit more from makita,
so i pulled an old flywheel key from an old victa and gave it quick run over with a file by hand to make it fit, knocked it in there was a little bit of the flywheel missing but the oversized key made up for it
now the only problem i have is the cluctch is realy noisy
sounds like a bad ringing sound untill it engage's im pretty sure its all balanced cause at over 60% revs it all works fine is it posibly loose springs on the clutch shoes and there just rattleing around?
you can just hear the ring at the end of the pull from the starter cord should they be engageing in a higher rev range? any ideas would be great just to make sure its sorted next time
thanks guys regards steptoe
