    Holla all. This is my first post here. I run a neighborhood lawn service (im 15) and have about 15 lawns a week and growing till about the end of october, and with all this use my husqvarn weed whacker isn't working right.

    It will run for about 5 mins, then shut off, then run for maybe 2 mins then shut off, then it wont work at all, well maybe a few seconds but then off again. I have a new spark plug, air filter, the correct gas mixture. It also will leak gas when it is hot, but not when its normal tempature. My plan was to get it serviced, but the turn around time is 2 wks for every shop in my area, so It looks like I have to fix this myself. I am thinking to replace the fuel filter and all the fuel lines, but can't think of anything else to do. Also, I have opened and closed the cap to mk sure it is getting air and keeping presure, but that doesn't seem to work. I have about 3 days too till I must use it.

    1 option is borrow or rent a weed whacker and take mine to the shop to get by for the next 2 wks. or

    2 get mine serviced and just buy a new one also, seems like it would be a good investment and good to have.

    Regardless, I need to figure out the problem. Any help or advice would be great! Thanks!

    If it stops working only when hot, then its probably the coil.
    Not sure about your leaking gas when hot problem though.

    Are you buy any chance getting any oily residue around your muffler exit? If so you may want to pull and clean(burn off) any carbon buildup of the antispark screen in the muffler. I would see no need to replace fuel lines unless they are leaking. Replace the in tank fuel filter and see if anything changes.

    I'm voting that it's the coil, though the fuel leakage does sound a bit weird.

    I recommend that you fix the fuel leak first and then work from there.

    It depends where the fuel leak is. The tank shouldnt be under pressure. the intake will suck the gas in no matter what, if anything, you want it to vent properly. If it isnt venting, it might not run right. I had a chain saw and the plastic fuel cap swelled up due to the gas affecting the plastic cap. It was a common problem with the saw. The cap couldnt vent right and the saw would stall out under load because it want getting enough gas. Even if your not trimming, its always under load because it has to spin the shaft and head while its idleing.

    If the carb is set too rich, it might not be burning all the fuel and that could cause a "leak". Unless you know how to tune it right, I.E. setting the high, low and mix screws, I would take it in. If you set them wrong, you could fry it. Even being set too rich can fry it. I would say its most likely a carb setting or maybe some crud is stuck in the needle/seat valve causing it to flood.

    After it stops working is the spark plug wet? Where is the fuel leaking from?

    what is the coil? Where is it located? I dont think Im getting oil from the muffler, but will check the anti-spark screen and try and clean/replace it. The fuel leak is coming from where fuel lines that go into the carburator and the carburator area. The lines look like they are just hangin on lightly, feel loose and worn down. The carb is set to stock, never have needed to touch it in all the many seasons I have had it. The cap is venting properly too.

    Thanks for all your help

    The coil is the part that generates the spark for your plug. You know the black wire that you put onto your spark plug? That is connected to the coil. When coils go bad, they lose spark when they get hot.

    Ok, thanks. Are coils universal or do I need to order the specific part. I just installed a new fuel filter and fuel lines and will go out and try to find the coil
