tight chain feel blunt

[jose]

My guys put a new chain on a 201 top handle, groundie did up up to tight. The climber  used it for a couple of days before i realised and loosened it a bit but it feels dull. Nothing has been hit and it all looks good but just doesnt cut like it should. 

Is it possible it got too hot which has affected the actual chain ( ie heated up and cooled too rapidly)?

Or can anyone else think of why it now feels dull. I havent sharpened it yet as it looks factory sharp still and ive never been able to improve on a brand new chain.

Its a Stihl chain.

Cheers

See , I have aleways been able to improve on a brand new chain . I would at least give it a tickle before you junk it . What you got to lose ? .

Not too loose Stubs, Too tight!

 

If it’s been work hardened the file will slide run through without taking any metal.

Bugger the chain, what about the stress on the clutch side crank bearing, it is always the bearing or seal on this side that goes! Hopefully a day or twos use hasn't messed it up.

The bar rails may need dressing

This could be the issue, the rails may be splayed with the heat caused by the excessively tight chain being run, the chain could now be moving slightly from side to side in the groove and not cutting properly.

Sprocket on the bar tip is after burning up from being pulled backwards by the chain. Take off the chain and see will it spin freely, I usually use the blow gun on the compressor to spin it up.

Cheers for the replys!

As said nothing to lose but thought id ask first.

I will give it a tickle hopefully this weekend and see how it goes.

Cheers guys

I would give your climber a kick up the arse for not checking the chain tension himself.
