Hello folks, new to the autotune Husqvarna's.
Anyhow I have a 545 here that has been such an absolute pain in the rear. The saw had supposedly sat for a year or two possibly and would only now start with much fuss usually flooding itself out in seconds.
So I went over it and found a busted primer bulb and replaced that with a new one. Put in a new spark plug, flushed out all the old fuel, made sure the filter was in place and everything else seemed to be in order. Good strong spark and the decomp appears to be functioning correctly? (more on this in a moment).
So now I have only gotten it to fire on two separate occasions. Both of these were when the saw had been sitting for a day or more and would only start and struggle to idle while acting sluggish (very rich feeling) and then die. After this on both occasions that it did start it would not ever fire again after that little run. Fuel would just spray out of the decomp when it was pressed during starting (is it normal to see excess fuel spray out of the decomp or do I possibly have a leak?) Then fuel would just start running / spraying out the exhaust and I have had to remove and drain the muffler now several times as it would fill full with fuel. I have even once removed the air filter to see the entire throttle body full of fuel there too, totally submerging the choke plate. Then if you hit the throttle all of that fuel would just pour down into the crankcase..
So WHY is this stupid thing asking for so much damn fuel all the time?? I'm hesitant to open up the throttle body (carb) as I have been told there isn't much to service there and I don't want to tear it open just to have to replace the gaskets if there's nothing I can clean or check? It's all automatic?
Sounds like this is dealer special since there the only ones who can work on these damn autotune ********. Any recommendations on going that route also and what to say or ask for?
Thanks good folks. I sure do appreciate the help. This one has had me cussing already haha.
