Question about Garden

1 Answer

I can get the trimmer to start, eventually, probably fuel, I use stabilizer but fuel is from the spring. Upon starting the trimmer does not like to be accelerated and stalls sometimes, does accelerate better if I start with throttle wide open first but after a few minutes it just shuts off. I can restart but shuts off again, almost as if the kill switch is engaged. I have checked the spark plug, looks good, will get fresh fuel, may not be the problem, and have taken off the arrester? which I understand burns off any extra fuel, although it does show some build-up the screen was not impeded in any way, the screen was a round cylinder which I just flipped over and reassembled. Any help would be great, I would hate to have to buy a new trimmer, this one works great and seems to still have lots of life in it.

Definately try new fuel mix. Gas (in USA) is usually 10% ethanol and loses its volatility in as little as 60 days. Stabilizer helps some. It sounds like this trimmer either needs an adjustment to the low side of the carb, or a rebuild. If it has adjuster screws, turn the low side out 1/4 to 1/2 turn and retry. You may have to remove the plastic locks on the screws, or some of the modern carbs require a special tool.
Good luck !

Dirty carburetor... Remove carb and clean it or have someone clean and rebuild it..also sometimes draining the fuel out and putting fresh fuel with Stabil a fuel additive sometimes will clean it out if you can keep it running long enough

Does the gas have to be drained

i would strongly recommend this especially when being stored for quite some time since todays gas the ethanol normally destroys carburetors keep fuel in tank treated with stabil or lucas fuel stabilizer and carb dry so when your ready to use it all you do is turn fuel on wait 5 seconds and your honda will start.leaving fuel in carb will eventually varnish and destroy them.

Weed trimmer starts and then dies repeatedly

Yes this could be the cause of the problem, it sounds like a fueling issue, fuel/air mix. Is fuel getting into the cylinder or can it be seen leaking out between the carb and the cylinder.?

I had purchased the Craftsman 32cc grass trimmer.Model # C944.515570.I took it apart to discovery that all the fuel lines had disintegrated.Clear lines were mush.I don't want to put the same type of line...

The fuel lines you're getting in the kit are the proper ones. The only problem these fuel lines have is dealing with gas that has ethanol in it. The ethanol degrades the fuel lines, primer bulb and some seals in the carburator making them very soft (mush) and eventually fall apart. Most outdoor power equipment fuel systems are not made to deal with fuel with ethanol additives. Sorry but if you can't find gas without ethanol added in your area, you'll have to keep some extre fuel line around.

Whilst cutting my hedge, inadvertently, I allowed my trimmer to run out of fuel. I refilled it and when I tried to start it, the engine spluttered then stopped and I have been unable, susequently, to start...

The fuel line probably has become air locked .Keep pressing the primer bulb if the trimmer has one and also repeatedly try to pull start the machine with the choke on. Eventually the air should be flushed from the line.

I have a craftsman 32cc weedwacker line trimer. Having trouble starting it. I noticed that the fuel lines didn't look to good so I replaced both. Installed a new spark plug and put in a fresh tank of gas...

Sounds as if the Carb needs to be cleaned out. Get yourself a can of non-chlorinated brake cleaner and spray the carb out really well. Then reinstall the carb. Also check any ports in the carb to make sure there isn't any debris blocking the flow of fuel. I would also suggest getting some Stabil Marine (blue) fuel stabilizer. The ethanol in gas destroys small engine carbs. Just mix this in with your gas tank the next time you fill up. How old is this fuel? The ethanol also absorbs water, so even while in the gas can it is obtaining moisture. The Stabil Marine formula helps lesson the effects of the ethanol.

Been sitting all winter with stabilizer in gaswon't start.trys but won't stay running.should I try draining gas and replacing

You'd be better off removing the float bowl and jets from your carb. I see this a lot in the early spring. People tell me they put fuel stabilizer in the tank but they still have problems. The reason is they treated the tank fuel but didn't run the engine long enough for the fuel to get into the the carburetor before they shut the bike down. Personally, I prefer to drain the carb before a winter storage. Pull the float bowl and the take the jets out of the carb and clean them out. That will probably fix your problem.

Good Luck

My troy-Bilt 5550 watt generator will not start

First drain the fuel bowl. Any old fuel in there will keep it from starting. Fuel stabilizer is not what it's it cracked up to be. I've worked for 6yrs at a rental yard and had no luck with any fuel stabilizer, the fuel still went bad. If after you drain the fuel bowl it still will not start, you will need to clean the carb. Remove the carb and spray carb cleaner through all the accessible passages. If this does not do it, you will need to replace the carb. For long term storage I highly recommend draining all the fuel and filling just the carb with fuel stabilizer to keep gaskets moist. Then drain the carb when you take it out of storage.
