Need some Weed Wacker help...(with video)

    So I got out my weed wacker and tried starting it for the first time in like 8 months. It wouldn't start. I figured the gas may have went bad.

    I took the carburetor completely off and disassembled it and cleaned it carb cleaner.

    I put the engine back together and put fresh gas in it and it started right up.

    The problem is I can't give it full throttle. Every time I gas it too quickly or too much it dies down.

    Anyone know what my problem is and how I can fix it?

    Thanks

    Almost every one I've ever owned/used would cut-out like you describe until the engine warms up.

    After about 2 minutes of running, I can throttle however I please.

    (Make sure you run e-free gas, or treat the gas if you store with gas in there.)

    Thanks I'll try letting it warm up. Although I've been running it for a while now with no luck.

    The little primer bubble just cracked so now I have to run to Home Depot to get another one before I try starting it up again :steamed:

    Check the plug/wire. If you repace it make sure the gap is to spec.

    Check the air filter, and replace the tiny foam fuel filter :) should run fine

    May have to run the "choke " 1/2 way till it warms up.. Just one of the quirks of small engines ..... :wavey:


    If that doesn't fix the problem, the air/fuel screw may need some adjustment. and its done by "ear"....

    #1. Start it with the choke closed.....wait a min or so. Open choke then aait a bit more. May just be cold and old

    In addition to what was already posted. It sounds like you have a restriction so it isn't getting enough fuel (after warm up).

    I had so much trouble with small engines the past, that as soon as I get a new one I cut the fuel line and put in a very additional small particle filter in a location where I can get at it without taking the system apart.

    Many times I've found a grain of sand in the carburetor inlet. Now, problems are gone and years of good performance (always with fresh gas and clean plugs too).

    OK. I just replaced the fuel filter and all the lines and the primer bubble. It now starts and runs like a champ. Except when I gas it it still dies :crying: I can get it almost to 50% but anything past that it just dies.

    I guess I'll take the carb apart one more time and blow some cleaner and air through it again before I completely give up :dunno:

    Adjust the screws. They probably need some tuning.

    An air leak in the fuel system/carb will cause this too. Wide open throttle is just more air. It seems to have more then enough already. See if everything is tight and lines don't have a crack in them.

    If it is too much air (leak) use more choke with medium throttle. If choke helps, look for air leak. Maybe something you forgot to tighten or connect. If choke makes it worse, too much fuel (rare problem) flowing through, look at float adjustment.

    I use a siphon line from my compressor air nozzle, to suck on the carb inlet and various places to clear debris.

    There are none. Only the idle screw which is fine.

    Just when I was about to quit :crying:
    OK I'll go try that. All the hoses are new so no cracks. If I had to guess I'd say too much fuel. I'll go try to choke it a little while I gas it.

    Choke made it way worse. It also floods very easily. Maybe I didn't get the carb back together the right way. I didn't even see a float in it. :dunno:
    Doesn't look anything like old motorcycle or car carbs.

    Those little primer bubbles cause a lot of trouble and need to be replaced regularly. They get a tiny crack and let in air and that's why you loose throttle response. When they get big cracks you won't start the thing at all.

    Fresh gas matters a lot in these small engines.

    This same thing was happening to mine earlier this season. EXHAUST RESTRICTION. Plugged with debris, especially likely after 8 months of storage. Cheap fix.

    This is going to sound smart-### but I don't mean it this way at all...

    Read the instructions on how to start the weed-wacker and follow them exactly. I have a Homelite that I always had trouble with until I followed the starting instructions exactly. It would run but it had to warm up and would cut out at WOT until it warmed up completely.

    I followed the instructions exactly and it starts and runs great every time.

    Also - try to avoid gas with Ethanol in it. It's bad for small engines.


    (Note - I can't watch the video but the above is just a lesson I learned.)

    Is this something you did yourself?

    I had one that did exactly the same thing.The spark arrestor was clogged.I took it off and threw it away and it ran like a champ for four years before I gave it to my brother.He's still using it today.
