Question about Craftsman 25cc Gas Line Trimmer
Where do the two gas lines hook up to. I took it apart and three of them came lose. I find the smallest one, I don't know where the other 2 go.
>>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.

Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Be Happy. Thanks.

The longest, and sometimes smaller in diameter of the two fuel lines, goes from
the carburetor to the bottom of the tank. Leave enough slack in this
line so that the filter that attaches to the end will rest comfortably at the bottom of the tank.
The other fuel line goes from the primer bulb to just inside the tank, (about an inch). make sure that you get the right size fuel lines. The plastic coupling goes on the end of this line, inside the tank. This keeps the line from pulling out of the tank.
(HINT): When feeding the lines through the tank holes, cut the lines at an angle. They will feed much easier into the holes. You can than cut them off square, once you know that you have enough to work with.
If you need further assistance, just let me know.

Hi this is the way it should go: 1 from the filter in the tank to the bottom of the carby,2 from the top of the carby to the inlet on the primer,3 from the outlet on the primer back to the tank as this is the return line nothing goes onto it.

Low side adjustment on the carb needs to be opened up or the carb needs to be overhauled. To open up the low sie, find the carb jet adjustment screws. The screw closest to the cylinder is the low side. Turn the screw counter-clockwise 1/2 turn. You may need to romove tho plastic locks from the adjustment screws, or if it is fairly new, you may need to buy a special tool to use on these screws. The tool is available anywhere that sells Poulan parts. If adjusting the screws doesm't fix it, the carb will need to be overhauled or replaced. Check with www.searspartsdirect.com . Replacement carbs are sometimes cheaper than an overhaul.

Looks like you've possibly referenced the wrong model # for your trimmer. There is a diagram available for model 358.791520, but not a 356.791520. You can find it here - http://www.searspartsdirect.com/partsdirect/part-model/Craftsman-Parts/Grass-trimmer-weed-wacker-Parts/Model-358791520/0247/1503820?searchedModel=791520&blt=11.
Once you get the Sears numbers for parts you need, you can find replacements for them at HyperParts.com's cross-referencing page here.
