Stihl MS 660 - (are there any Stihl service guys out there!!)

[Old Mill Tree Care]

At the risk of upsetting someone, if you're taking it to an authorised Stihl service centre look to see if they sell chainsaws as well.

I've got three tools over the last four years "written off due to seized piston" by Stihl centres.

Don't waste your time or stress, send it to Spudulike.

Not being funny but we are talking about a MS660 here - cast iron heads were found on 60s-70s kit like big Danarms, Homelites & old McCullochs etc almost all modern saws are Nikasil plated aluminium:confused1:

 

yeah ive no idea about chainsaw motors in terms of what materials are used - was going by 2 stroke moped motors - some of the air cooled ones still use cast iron heads....

 

as far as im aware you can heat seize a motor just by not letting it warm up and flogging it regardless of what kind of air/fuel mix its running on? but if it had heat seized it wouldnt be a case of it not being able to start - it would be locked solid and would have stalled prior to that?

Thought so - no worries, learnt many of my skills on Honda fours and mopeds then went on to cars and now saws, still gives me a buzz when you turn a knackered saw in to a runner.

 

Not really come accross cold saws seizing, they are usually a little boggy when really cold and a few minutes warm up is normal procedure.

 

Most of the seized saws I have had through have seized then freed up and the normal issues are old or bad fuel, poorly adjusted carbs or air leaks - got to remember that some of these saws are revving at 13k - 14k rpm, a fair bit higher than many of the old two stroker bikes.
