Try spraying carb cleaner inside the carburetor. Left over gas will clog the tiny ports inside the carburetor. Next time either add stabilizer in your gas tank or run it dry until next season. Good luck!
Fall is here and now is the time to winterize your lawn equipment. <br />
If you plan on using your equipment into the winter, then this is the time to stabilize and winterize your fuel. If you have any fuel left over from the summer, use it up now and get fresh fuel for the winter. Gasoline starts to "oxidize" in as little as 60 days. So take the older, stale fuel and use it up. Mix it with the good gas in your car if you have very much left over.<br />
To winterize your fuel, start with fresh gasoline. Buy fresh gas from a station that sells alot of fuel, that way you are getting the freshest fuel possible. Add a stabilizer to the gasoline. I use "Sta-bil" brand, but you can use any brand of stabilizer that is local to you. Read the directions on the bottle and mix it with the gasoline. Fill the tank on your equipment and allow it to run for about 5 minutes. This will make sure the stabilized fuel is in all sections of the engine that have gasoline. Top off the tank and then store you equipment in a dry area. When spring comes around, you will be ready to use your equipment.<br />
If you are still using your equipment, prep your fuel as above and make sure to top off the tank after each use. A full gas tank is less likely to absorb water from the humidity in the air.<br />
This is also a good time to check the air filter.<br />
We'll change the oil and sharpen the blade in the Spring.<br />
No what the problem may be is the gas tank filter may be stopped up or the carburetor has varnished gasoline in it? In the future use an additive called stabil can be found at most auto parts stores or Walmart has it in automotive around the gasoline additives! It gasoline from varnishing and becoming gel like in the winter when you store your mowers weedeaters and tillers! Try getting gasoline to be pulled up by making sure gas flows from fuel lines first! If you don't have a primer button then you more than likely have a choke on the carb? Close the choke you can use ether sparingly to ease in pulling the rope frequently or a rag soaked with a little gas will allow vapors to get sucked in the carb assisting the engine to start
Clean or change air filter. Clean, gap or change spark plug. Empty gas tank add fresh gas with Stabil. When spark plug is removed pull rope several times to blow out cylinder. Spray starter fluid in spark plug hole before replacing spark plug. Clean outside of carb so choke works freely. Spray starter fluid into carb breather hole with air filter removed and try to start. if running replace air filter and cover. If no start disassemble carb and clean. If no start replace carb.
My wife once mistakenly topped off the tank with diesel instead of gas. Same symptoms. Gas also goes bad when it sits in a tank for several months without a stabilizer. Try adding a fuel stabilizer and filling the tank with high-octane premium gas.
Yes. Whether storing your saw for a week or a month, a quality fuel stabilizer adds life to your saw. It can also keep it running with the type of problem your having. Double the recommended strength in your mixing fuel can and replace the fuel in your saw. Remove the spark plug and shoot a 2 second burst of lubricated starting fluid into the cylinder. Replace Spark plug and start your saw. Let it run for at least 2 minutes with the choke on then slowly increase the rpms as you push the choke in. If your saw stalls inside of that 2 minute window, do this procedure when it begins to stall out. If it still will not run, then your jets ( located inside the carb) are plugged up with varnish and you may need to rebuild the carb or replace it - it would be cheaper to rebuild and this is not a difficult job. If you choose to rebuild, get some starting fluid without lubrication to soak the jets in as you clean all the other parts. The starting fluid has a high level of Ether which will break down stubborn Varnish deposits.. Rinse all the parts in your fresh fuel mix ( oil, gas, and stabilizer). Re - assemble carb and flush your fuel tank as well. Put it together and then shoot a 2 second burst of lubricated starting into the cylinder through the spark plug hole. Install spark plug and follow starting procedure, foregoing the primer bulb. Your saw should now be running smoothly unless your carb is defective. Good luck!!
If you leave gasoline inside tank over long period of time, that will 'gum-up' and ruin carburetor. To prevent problem, put additive in gasoline or empty gas from tank:: under gas tank should be a hex bolt that holds up gas filter > loosen bolt and drain gas.
Starting the engine: Take off air filter and spray WD-40 directly into carburetor. Start engine, engine should fire on the WD-40 accelerant. If engine fires but does not keep running, try spraying WD-40 into carburetor continuously to see if you can keep engine going. If engine stops each time after it no longer gets WD-40, then carburetor is bad or gasoline not getting to carburetor or gasoline is bad. Try fresh gasoline. Do not turn small engine on side or upside down or oil will get into carburetor.
Check gas supply: Go to gas filter under gas tank. Pull loose rubber hose that connects to carburetor and see if gas comes out rubber hose. If gas is flowing to carburetor, then carburetor is gummed up. Small engine repair might suggest 'gum out' or have other suggestions ... but you may need a new carburetor
If engine will not fire on WD-40 If engine will not fire on WD-40 at all, then spark coil may be bad or exhaust port is clogged Check screen that covers exhaust >> is it covered with carbon and dirt or can air pass through it easily? Check spark Remove spark plug Put spark wire back on spark plug Hold spark plug by rubber spark cap so hands don't touch metal part of spark plug Touch spark plug threads against hole where spark plug was removed >>> metal to metal so it conducts electricity Pull start cord and look for sparking between spark plug threads and metal of engine (don't look at the spark gap ... look where metal meets metal If you have no spark, the spark coil is bad >> time for estimate from small engine repair shop or get your part number and order replacement
Is the spark plug black? It won't run well with a carbonized plug.
Is the main jet in the carb plugged? If the plug is dry after trying to start it.....your fuel is not getting into the engine and most likely a plugged carb jet.. Also.....Is the fuel switch working...is it in run position?
If the generator has sat for a while with fuel left in the carb/fuel tank.......the most common problem is a plugged varnished dirty carburetor in need of a good cleaning. Always shut the fuel off and let the carb run dry (run until the engine stops)before storing. Add fuel stabilizer to any remaining fuel or drain the tank before storing.
Empty out the gas and replace with proper gasoline mixed with oil in the proper proportion. Always use a good quality 2-cycle oil that contains a fuel stabilizer. To start the generic chainsaw, follow these steps: 1. Pull the choke all the way out 2. Press the fuel bulb serveral times to prime the carb - you can feel when the fuel flows into it. 3. Set the lock on the trigger to full speed. 4. Now, pull the starter rope until the saw sounds like it tried to start. 5. Press the choke in to the 1/2 way position. 6. Pull the rope until it starts. 7. Release the trigger lock and push the choke all the way in.
If starting it when it is warn, skip steps 1 and 4. It is unlikely that the spark plug is the problem. If you replace it without properly setting the gap, you may make it worse. If you start trying to adjust the carb without knowing exactly what you are doing, you will make it much worse, You can try spraying some carb cleaner into the carb and pulling the rope to such the cleaner into the jets. In the future, always add fuel stabilizer or oil with a stabilizer to you gas/oil mix. This prevents the varnishing caused by aging gasoline.
