560xp cutting out

[Acerforestry]

One of my 560's is under a year old with minimal hours, that has become such a pain I will probably give up with trying to get anything done on warranty as its still running really badly even with a new carb. Really difficult to start, and even once warm will cut out on tickover and then only fire up again with drop start with throttle. Any suggestions before the bloody thing goes on ebay, thanks

It’s always difficult giving a diagnosis without actually seeing it, however when you say new carb is that from another saw or a new carb that a dealer has correctly entered the firmware ? ( all new auto tune carbs come with just boot firmware ), now does it have the orange frame air filter? these filters block very easily even though they look clean so make sure it is very clean, a pressure test would be my next thing to do, if you could get it plugged into cst it would give some clues by looking at the fuel settings, unfortunately any loss of compression will effect the idle, so is it mechanically sound ( seized, ring wear etc ) things like plug change and fuel filter change should always be tried as this is easy to do. It goes without saying that these machines rely completely on cooling air entering via the starter housing grill to cool the engine, so keep all openings free from blockage ( additional heat will effect running and hot restarting ). Leakage from the deco valve will also effect idle, I have blanked deco valves off in some cases.

Do you repair saws? Could I send it to you. The dealers are not having much luck with it so nothing to lose.

560 just out of warranty hardly any work......I call crank seals....air leak causing hard starting and poor performance.

That has occurred with another 560 or 62 previously, and has also affected colleague's saws as well. Husqvarna seem to have dropped the ball somewhat in recent years, these are 900 quid units and you expect better really

Get it fixed and sold on, then put the money towards a brand new ported 346xp from customsaws, it will see you through till retirement. 👍

Yes, probably a good call, has now gone to Haynes Agricultural for another assessment. Hope it's going well over there

I know a few people that have had the problem. I'm lucky and not had it.  Apparently it's because the bearing cages are plastic now.
