I've never had spindle problems. Just the double deck drive pulley bearing, replaced one and less than 150 hours later replaced it again.
I did have a major loss of power from a bad plug that only seemed to miss under load. also, check that the air flow through the shrouds is clear.
My manual says every 300 hours for a valve adjust.
