husqvarna 575xp conks out when in use

[hazelnut]

Hi there,

hope someone can help without me taking it to the local rip-off repair shop.

i have a 2006 575xp and it starts,ticks over fine as soon as i use it and it gets hot it loses power like it has a fuel lock then stops,it starts up again straight away then repeats the fault again..the saw had a new bottom end fitted a year ago and i run it on a good stihl oil mix.could it be a carb fault,i have cleaned it now a few times,the cylinder head is tight.could the ignition coil be at fault or the carb?

thanks

First remove the fuel cap, run it on its side, if it revs fine, it's the breather, if not, try richening L screw about 1/8-1/4 turn

I was going to say compression at first, but it starts up straight away.

 

Then I thinking fuel tank vent blocked.

 

Or air filter blocked.

 

Could also be plug or coil.

I've sold many of those saws and I also sold many coils, carbs, and pot and pistons for these machines, magnificent saws while 100% bit gave a lot of problems.

We had a 575 in our armory and it scored a piston after about 6 months from new . I seem to remember there being a bad batch of fuel lines that perished prematurely allowing it to run lean causing it to nip up . It was peculiar to 575s only for some reason . Never loked it anyway . Much prefer a 372 .

does it only do it when its hot?? because mine done the same and it was the plug stopping sparking when it got hot changed it good as new love that saw
