Ok can you check for any play in the blade plate as it could be noise from worn bearings.
Bruce,
Briefly checked for play when I replaced the blades. Nothing out of the ordinary, I thought. Mind you, I wasn't really doing it in a 'serious' way, so will have to do again and be a bit more precise.
I should say that I've worked on/rebuilt/modified all types of engines over the years....cars/motorcycle...2 stroke/4 stroke...single cylinder/multi cylinder. So pulling it down to find the cause doesn't phase me. I planned on a decoke over next winter and given the noise is not too bad (by my ears....I've heard worse) I'll still do that but go a bit further and do a complete strip and check.
Do you have an info/diagrams/specs on this model ??
Thanks
