Get a rag and rub a bit of chain oil on the bar before you use it.
When bedding a new engine in…
Try not to Rev it too much outside of a log.
After each tank of fuel, give it 45-60 minutes to cool.
Keep the chain tensioned correctly.
If it sags after a few cuts,normal for a new chain.
When you’ve retensioned and finished the first tank YOU MUST detension the chain or it will stretch as it cools possibly bending the crankshaft.

Saul what makes you say that not detentioning the chain can possibly bend the crankshaft,cos i,ve never heard or experienced it

Saul , you have seen a crank shaft snap/bend due to a chain contracting after it has cooled down ?

So the threads in the chain tensioner held but the crank bent?

 

And the barstuds stopped holding the bar?

 

And the crank bent past the outside bearing?

 

All from a tight chain cooling down?

 

Lies.

Back in Brighton about 6? Years ago,
There was a lad selling used power tools in a unit opposite.
He brought over a 361 one day and asked if it was any good.
When I pulled the starter cord the chain started moving, without the engine starting.
Interesting I thought, so took off the side cover, bar and chain. When I pulled the starter cord the whole clutch housing rolled around, and not the way it should do.
The bar and chain were toasted with burnt crap.
Presumed over heated chain with repeated over tensioning then left to go cold.
Can’t see any other way that could have happened.

If you connected a chain to a crank shaft and anchored one end and the other to a tensile testing machiene I am pretty sure the chain would snap before the crank shaft .

Ok. You supply the saw, I’ll supply the chains.
Let’s test it.

I am not agreeing with you, you are making stuff up to try and cover up your lack of actual experiance.

 

You got knocked back for job as a groundy at a council up north ffs. Thats where your experiance lies.

A broken clutch spring will engage the drum and spin the chain.Did you pop the drum off?

 

You know FA about saws mate.
