Husqvarna 350 Problem

[ADBACL]

I wonder if someone can help. I am new to Huskies. I just bought a used 350 from private owner, who had it serviced by a licensed dealer (have a receipt for it). I have no problem starting it. As soon as I lay it on the side it stalls soon. I checked fuel and oil and it is all OK. I then try to start again and it has some trouble. Once it starts again it stalls quickly again after few seconds. The dealer installed new muffler, chain, guard, heat deflector, gaskets.

What may be the problem?

Thanks for your help

I'm not an expert but it sounds like you need to rebuild the carb.

Try changing the fuel filter. If that don't work you may have an electrical problem. I would also try a different servicer. But, it may just be the fuel filter or need the carb rebuilt. Fuel filter would be the simplest thing, so I would try that first.

It could be a couple of things, but this comes to mind first.

When you lay it on it's side and it dies. You say it is hard to start after that? Check the plug the next time it does it. See if it is really black, like it is running rich.

Sometimes when a carb is set too rich on the low idle, it will stall when put on it's side. It will stall because the excess fuel in the transfers makes it way into the piston and can foul the plug. If this is the case, simply screw the L side jet in about 1/8-1/4 turn (clockwise) and recheck the idle. You may have to lower the idle screw to keep the chain from spinning at idle. Again, only perform this procedure if the plug looks extremely black like it is flooding.

Could also be set to lean at low idle. the plug should tell the story when it does it again. But normally when they are lean on the LOW side, it will hesitate and sometimes sputter upon acceleration.

It could also be the seals are worn and sucking just enough air, but at this point I think it might be the carb is set too rich on the low side, but again, only the plug will tell.

I know that alot of the Huskys I work on have a hole in the fuel line where it comes out of the fuel tank. Try inspecting the hose.

Agree with that observation - as well they sometimes get a crack on the inside of the tank where the hose enters the tank - when in a certain position this crack may open up, and it will suck air...

Checkt he filter and the line carefully all the way to the carb - and it is worth checking the plug as well like mentioned above...

I tend to agree with Stang's theory on the low speed being to rich. If you notice lot of smoke when you get it started again, then that's what needs to be adjusted.

Also agree that you should check the fuel line. If you leave it on it's side does it leak any gas? We see so many fuel line failures, that checking them is now part of the regular servce.

lines

While your in there might as well check impulse line.I had one that looked good.Stretched it, pulled it looked good.Went nuts adjusting carb!Darn line was bad.Couple of inches of line cost me a lot of time!

I had the exact same problem on a ms 310, turned out to be a cracked fuel line between the tank and the carb.

I with steve

But I have a question does it only stall on one side or both?

the plug check will tell us a lot also.

That's where my money is. Start out as cracks, then deepen into holes, ultimately severingthe line altogether. Cheap, easy, quick fix, too.

Thank you

I want to thank everyone for the help. I will try to fix the problem with my Huskie over this weekend. I will keep you posted.

To answer one of the questions. The saw stalls when I switch to either left or right side. It cuts OK, when I hold it straight, but as soon as I create an angle and start cutting, it stalls quickly.
