Open Question

Craftsman 24cc/1.46 cu. in. 2-cycle weedwacker was idling too fast and stalling out the last time it was running. I put a new spark plug in and replaced the fuel with new oil & gas mixture. Now it won't start.

SOURCE: I need to know the gas mixture ratio for a craftsman weedwacker

Hello mcguilmd:

>>All Two Stroke Engines will use a 50 to 1 Ratio using Today's Two Stroke Oils. I once had an Old Chainsaw probably from the 1950s, maybe Earlier 70s that had a sticker on it that said to use a 25 to 1 Fuel/Oil Ratio, but that would have been using Two Stroke Oils of the Time Period the Chainsaw was Manufactured. I was having a Problem with Oil Coming Out of the Muffler and Started Decreasing the Oil in the Gas. I Reduced the Oil Until it was a t a 45:1 Ratio and Decided to be Safe, I would Use a 40:1 Ratio Mix. In that Chainsaw I used 50 to 1 Ratio with no problems. Today's Two Stroke Oils compared to Yesteryears are more Efficient at Lubricating. It is like comparing Today's Synthetic Motor Oil to Motor Oils of Decades ago. All the Equipment I use in Landscaping, anything from a Weed Eater, Leaf Blower, Chainsaw, Hedge Trimmer, use 40 to 1 ratio, and I use all types of makes and models, Stihl, Homelite, Husqvarna, Shindaiwa, and Echo, Sears. I mix up a 5 Gallon Fuel can and use it in all of the Equipment for my Customers and for my Landscaping. I like my Fuel/Oil Ratio a Little Heavy, so I use a 40:1 Ratio. The Following was Copied and Pasted here from and MTD E-mail to me when I Asked for the OEMs Suggested Mixture for this Unit. The mixture, as described by the engine manufacturer, is a 50:1 ratio when using the approved types of 2-cycle engine oils.
50:1 ratio is a mix consisting of 2.5 ounces of 2-cycle oil per 1 gallon of gasoline.
The 2-cycle oil used should be approved and have one or more of the following specification titles: NMMA TC-WII, TC-W3, JASO FB, or JASO FC. NOTE: If unsure of the 2-cycle oil specifications, or the oil is not approved, use a 32:1 fuel to oil ratio. This ratio consists of 4 ounces of oil per one gallon of fuel.
NOTE: Always mix 2-cycle fuel oil and fuel in an approved gasoline safe container prior to filling the engine. Make sure to use a separate gas can for this 2-cycle fuel mixture and label it accordingly. Keep in mind that the fuel capacity of these engines normally is less than a gallon, therefore you will have to use this extra oil mixture for multiple fuel fills. Adding a fuel stabilizer will also help to increase the shelf life of fuel.
>>I Suggest Using a 40:1 Ratio and if Oil Starts Coming Out the Muffler then go to a 50:1 Ratio.
Please, Do Not Hesitate, If I Missed Something or you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance.
Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Be Happy. Thanks.

Good Luck

Respectfully

SOURCE: The weedwacker dies when I squeeze the throttle trigger

You need to clean the carburetor. Remove and disassemble carb. Use a den Tek Brush, (used to clean between teeth), to clean the small portals in carb. Use a carb. cleaner while cleaning. Make sure the small screen in carb. is free of debris. The smallest of paticles can cause the carb. not to run right. Reassemble the carb. and try starting. If there is no change, then you will need to buy a carb. kit for your trimmer. Replace all appropriateparts: gaskets, diaphragm, needle valve, and the small screen.

SOURCE: craftsman 32cc would not idle

If you are certain that you have correcting gaped the plug then the next step is to readjust the low end idle carburetor. If you look you should see two holes in the plastic cover that lead to the flow adjustment screws they may even be out in the open. If they are not labeled H and L (the L is the one you want), check your manual for the correct one. A good place to start is turning the screw all the way in then backing it out 1 1\2 turns. Then check it. If you still have problems do 1\4 turns out. After about one full turn from that you might want to consider taking the carburetor off and removing the float bowl or the bottom for a good cleaning. A sticking float could cause problems with your fuel flow.
Hope this helps.

SOURCE: RYOBI Expand It 2 stroke engine. RY26000 won't

I had the same issue. I disassembled carb and cleaned. Started up, but ran poorly. Looked at a few google searches and found a forum about his issue. I came across a write up about failed muffler bearings. I did some research, but to no avail. on part numbers. I went to a repair shop and inquired about how to get a muffler bearing ordered for my unit. It has been about a week since I was at the shop and I did call, but they assure me that they are working on getting this part for me. Apparently these motor parts are made in China and that can create some issues when trying to get parts. I may have to let the repair shop do the repair since I was told it may be a bit complicated to replace without having the experience. If it is as difficult to locate, I would not want to damage it when trying to install and have to get another. I will be glad to repost once it has been repaired. Perhaps this muffler bearing is an issue with a lot of other units and we may be able to contact the manufacturer for a refund or a free muffler bearing? I hope!!! Good luck out there and hang tight. I may be on to something here, I've got a good feeling about this.

SOURCE: I have a craftsman 32cc

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.

You need three things. Spark, compression and fuel. Pull the spark plug and make sure it is not fouled and you have spark when cranking. Put your finger over the spark plug hole and feel for compression while pulling the engine over. There is a reed valve between carb and block that clogs and prevents fuel from getting to cylinder.

No spark


To test the spark you will need a spark plug tester. Put one end of the tester on the spark plug and the other in the plug wire. Pull the cord and see if fire is there. If not you will need to replace the coil.

Craftsman weed wacker will start and run


Are you sure you have the right fuel mixture? Many of these require 2 Cycle oil to be added to the gas. If fuel is right, you may have a vacuum leak at the carb (or crack in base where it mounts to the engine). My weedwacker needed to be run on half choke for about 10 min before it got hot enough to run with choke off.

Engine on Craftsman Weedwacker will not turn over.


I assume the tank has gas. The first thing to check is for spark at the plug. Remove the plug from engine, connect the plug wire to the plug and ground the side of plug to metal engine housing using pliers with plastic grip handles so you don't get a shock. Pull the starter cord and watch the plug for a spark jump. If you have spark then it is likely a gas starved situation. All these small engines should be run dry before storing in the fall of year to prevent carb from gumming up over the winter. Anyway remove the gas line and drain any gas from carb and drain tank too if it has old gas from last year. Replace fuel line and spark plug. Using new gas and 2 cycle oil, plus an ounce of STP gas treatment, refill tank. Work the primer bulb several times and pull the throttle several times, then pull cord. Keep repeating to see if you get a start.
