This is literally how I envisage you 2 at the moment

That's like my flywheel at the moment lol. Gareth is definitely in season!

Have you checked the clutch side?

Yes thanks.

Does it run at all between seizes or is it locking up just pulling it over even without the spark plug fitted ?

One of the guys said..."can you turn the engine over freely for one complete revolution once free". This is a very good question as it shows you if the saw has a problem at a specific point of the engines stroke.

If the engine is able to turn over freely for a few revolutions then the problem, most likely, lays with the recoil cover.

It is possible a circlip or ring has failed and the bits are loose in the engine causing it to lock up intermittently but spinning the engine over by hand in different positions will prove that.

No it doesn't run at the moment. Its locking up with and without the spark fitted.

Hi there,

Once I've freed off the flywheel when the pull assembly has been removed, the flywheel will freely turn over by hand. As soon as i refit the pull assembly, after a few pulls it will seize up again.

To be honest,. Explaining that better now, is a lot more helpful. What you are stating would appear to be isolated to the recoil unit. My earlier comments to help, were on the understanding the flywheel without the recoil fitted would only move by hand less than a full revolution before it '"locked' again. Or maybe I read your original post incorrectly

Had a similar issue with a husqvarna leaf blower. Turned out to be a casing screw behind the flywheel had come loose and fallen out, and was jamming behind the flywheel against the engine side. It moved occasionally and would allow the engine to rotate a few times, but would then prevent it turning. May be a possibility?
