576 problems any ideas

[MattyF]

576 has been acting up for last few weeks like it's over fuelling , today it's sluggishness and Incessant stalling really started to get to me so checked the plug and it was black ! Changed plug just to see difference and saw after a few cuts was just bogging down and stalling worse than ever and plug was white!!

Now the saw I recon has done around 5 hours and is a few months old the dealer I brought it from has lost all his saw technicians so I would like to go in with some idea of what the problem is and get it fixed ASAP any body else had 576 problems or an idea of what this could be ?

Sorry mate the 576xp had first generation Auto tune, so you cannot plug into the computer or re set the software. Seems abit strange you have gone from a black plug ( running rich ) to a whit plug ( running lean ).

Can you reset the auto tune at all on the 576? I've tried what usually works with my other 5 series saws leave it cutting flat out for 3-4 mins and it seems to have made the problem worse ! In fact I doubt you could get it too cut one ring in timber ! It starts up and revs but just won't do any thing under load.

The only thing we have had with our 576 was a tiny hole in the fule line that made it run funny.

No you cannot reset the unit, there was a bullitin about checking it useing a 12 volt battary, unfortunalty this did not achieve anything, check the fuel filter in the tank first before taking parts off, if the unit is playing up it is a new carb and unit combination, you could always convert it back to a standard saw.

Is the auto tune that poor on the 576 you would recommend converting it to standard saw ?

I'm lucky to have one of the last normal 576xps runs sweet

Lets just say i would convert it if it was mine, it is gen 1 and there is no further investment into this system. But as i say you need to make sure there is nothing wrong with the fuel system., converting it will not put right any issues that are not to do with the Auto tune unit.

Cool , Will look in to it then when I take it in and see if they can do it under warranty ...if they have any one capable of fixing it!
