Experienced gardeners share their insights in answering this question :
Has she been sitting for a long time? I would start by removing the carb from the engine and cleaning the carb. Remove the fuel bowl first. On the bottom of the carb fuel bowl should be a 1/2 (wrench) size screw. remove this screw and try to remove the bowl, be careful of the fuel bowl gasket, thin paper or an O-ring, use slow back and forth motion to remove the bowl. Now in the center will be a brass jet that will be clogged up try be careful be careful not to strip it out, use a flat blade screw driver and remove the jet clean it out clean out the carb as good as you can, put her back together and she should get back to work for you.

How to Identify and Fix Common Gardening Problems ?

A leaking snowblower carburetor float valve is the most common cause of a snowblower`s oil smelling like gas. Engine oil contamination is serious and can cause an engine to seize. The repair is simple, replace the float valve and change the engine oil.
For use with CRAFTSMAN® Single-Stage and 2-Stage Snow Blowers with 4-cycle engines. Includes: 28 Oz. Bottle Of Sae 5W-30 Engine Oil.
What causes fuel to leak into my engine oil? The fuel shut-off valve isn`t closed properly. Fuel float in the carburetor being stuck in the open position due to gumming (caused by stale fuel) or debris.
The carburetor gasket might be dried out or missing. If the leak is coming from the bottom of the carburetor, try replacing the carburetor gasket. Need help finding your model number? The carburetor might be cracked, or the carburetor float might be stuck open.
Product Overview. The CRAFTSMAN® SB2650 is powered by a 243cc 4-cycle OHV engine. The strong serrated steel augers cut through snow for faster clearing, saving you time on those frigid mornings.
This snow blower is powered by a 208cc 4-cycle CRAFTSMAN® engine that features push-button electric start to eliminate pull-starting a cold engine.
Craftsman 5W-30 Synthetic Blend Oil is formulated from high quality mineral base stock specifically for use in small engines applications in cold environments. It is designed to perform well in all temperatures and delivers easier starting in cold weather.
Answer: Dave, this Briggs & Stratton SAE 5W-30 oil is a non-synthetic oil. It can be used in all air-cooled 4-cycle engines, including snowblowers. This type of oil is recommended if operating temperatures are below 50 degrees Fahrenheit.
If the blades get worn they will not effectively throw the snow. Visually inspect the blades for excessive wear and replace if needed. Need help finding your model number? Inspect the belt to see if it is broken, stretched out, or out of place.
How Do I Locate the Engine Model Number on My Snow Blower? The engine model number is usually a number stamped into metal directly on your engine. It may be stamped onto the left side of the overhead valve cover, the metal shield below the muffler, or the cylinder shield on the side of the engine.
Don`t overfill the crankcase when adding oil. Too much oil can damage the engine. Briggs & Stratton offers oil specially formulated for your mower and other equipment.
A small amount of oil will not cause any major damage. However using 2T oil or mixing any oil with fuel in a 4 stroke is neither required nor recommend specially in modern vehicles. It will increase emissions. It may cause premature carbon build up in the engine.
Common signs include reduced engine performance, black smoke coming from the exhaust, backfiring, overheating, or hard starting.
Vacuum leaks can be located with spray carburetor cleaner or a can of WD-40. If the area is obstructed by linkage or hoses, use an extension nozzle to pinpoint the area of the vacuum leak. If the engine speeds up when an area is sprayed, you are close to finding the leak.
The ideal ratio of power to intake size on a full-sized snow blower with a 20- to 21-inch intake height is 8 HP to 24-inches in width.
Use carburetor cleaner to remove deposits, clogs & debris

Deposits inside the carburetor can clog fuel and air passages and reduce performance or stop the engine altogether. Luckily, you can take care of many of these problems quickly and easily; often without even removing the carburetor from the engine.

Two-stage snow throwers have serrated steel augers that break up snow and ice and feed the snow into a high speed impeller (stage-one). The impeller then throws the snow up and out of the discharge chute (stage-two). If you`ll be tackling heavier wet snow, then a two-stage thrower is a safe bet.
Look for professional snow blowers equipped with an engine of at least 400 CCs. Pick a snow blower clearing width that fits the properties you`re servicing. Biggest can be extremely efficient but it isn`t always the best option for clearing diverse areas like narrow walkways.
You can use 10w30 instead of 5w30 oil since both meet the SAE standard for viscosity at operating temperatures. Generally, the viscosity difference between the two is neglectable. However, it`s important to note that a 10w30 oil will move slower than a 5w30 oil in cold environments.
During the winter time a synthetic oil also provides a more even flow of the oil. Conventional motor oil contains wax, which can freeze or congeal at low temperatures. A synthetic oil is best since you will be using your snowblower exclusively in cold weather.
Here`s the rundown for our purposes here: In a pinch, while it`s generally OK to use an oil that`s one viscosity rating higher or lower than what the manufacturer recommends, it`s best to use the viscosity given in the owner`s manual. When considering 5W-20 vs 5W-30, they are the same viscosity when the engine is cold.
You can use 10w30 instead of 5w30 as long as the vehicle isn`t subjected to cold temperatures for an extended period of time. You want the oil to be pumped throughout the engine as quickly as possible after starting the engine to prevent “cold start damage”.
Use SAE 10W-30 for a varying temperature range of 0 to 100° F (-18 to 38° C), this grade of oil improves cold weather starting, but may increase oil consumption at 80° F(27° C) or higher.
Use Briggs & Stratton SAE 30W Oil above 40°F (4°C) for all of our engines. Check oil level regularly. Air-cooled engines burn about an ounce of oil per cylinder, per hour.

Which fuel line “port/inlet” on the Walbro wt-380 goes to the fuel tank? It’s on a Craftsman 25cc Gas “Weed Wacker” Line Trimmer purchased in 2002. It has Walbro WT-380 carburetor with external primer bulb. The carb has two inlets for attaching fuel lines – one to gas tank, one to primer bulb. One inlet is on diaphragm side of carb (side with the two Low/High speed adjustment screws). Other inlet is on “reservoir?” side (side with air/fuel mixture screw). Which inlet gets the “fuel tank line”? (Other will obviously go to primer bulb. I found all kinds of diagrams on web but none that showed this. Your assistance is greatly appreciated. (Problem occurs when replacing gas lines and forget which line goes where:)
ANSWER : Usually the line with the filter on it that comes from the tank goes to carb. inlet first which is most likely close to the bottom side of the carb.nearest to the engine,then the outlet or return line on the carb.goes to the inlet side of the primer and the outlet side of the primer goes back to the tank. The primer draws fuel through the carb to the primer to the tank if its not? then correct the line connections until it does
