Husky 576xp will not rev up

[David Griffiths]

I have been having a problem with my husky 576xp not wanting to rev up. I suspect the needle valve in the auto tune cab is getting stuck (properly because it is not my day to day saw and is not started for a week or so at times). I read you can reset the auto tune with 2 9volt battery's (making18volts) connected to the red cab wire and black earth wire and then open the throttle 5 times. I also read I should hear the valve click. I did not hear the valve click. I am not sure if I am resetting the auto tune properly or if my valve is getting stuck! Can some one tell me if I am resetting the auto tune properly or not? Thanks

have you checked your fuel line,i had one do similar and there was a small hole worn through it half way down causing it to struggle pickup revs,changed the pipe,hey presto

Do not do that, you're likely to fry the processor! To reset the autotune, either take it to a dealer or leave it on idle for 10 mins and turn it off.

I have checked the fuel pipe and found it has got a pin hole leak and the pipe which has been living in the fuel has become very soft. I will fit a new pipe and let you know how I get on. Probably best not to play with auto tune. Thank you for your replys.

If that's the case your basket filter in the carb will need cleaning I would of thought as well.

Just to up date you. I cut off the fuel pipe with the hole in it and pulled it through which fixed the problem until I got a new pipe which I have now fitted. thank you for your help : )
