DO NOT:thumbup: START THE MACHINE without the bar and chain in place - the clutch can spin off:blushing:

 

Mine made sparks on the patio when it took off down the garden, you only do it once.

On one of my posts I said: -

 

"If the chain doesn't creep forward, it sounds like you may have an air leak in the clutch side seal - I notice when doing leak down tests that these saws can leak if the crank is pushed to ones side - just down to the needle crank bearings and hardened seals! "

 

I would say that your chain brake is putting some sideways force on your crankshaft and that the seal on this side has worn or gone hard so is leaking air when the brake is on - fit a new seal!

Found the problem manifold has a split in it so sent it off for repair

Not sure how the chain break caused fast running but glad you found the issue!
