MY SAW WONT START AFTER I PUT NEW PISTON AND HEAD
Do you mean that you replaced the piston and cylinder? The head is built into the cylinder. If you did change these did you also change the crank seals at the same time? Are you getting spark? Is it getting fuel meaning is the spark plug wet with gas when you try and start it?
Have a makita gas cut-off
Is the gas fresh? Is the plug wet with fuel after you try and start it? Have you done a compression test on the engine?
What kind of gasoline i need?
According to the manual, "use unleaded regular gasoline with a
min. octane value of 91." You need to mix oil into the gasoline at a rate of 50:1 or 2.5 fl ounces of oil to one gallon of gas. If your saw has little power or is very hard to start, it may have been run with straight gas in which case the piston ring or cylinder or both may be damaged enough to warrant replacement.
My saw has fire,it just will not start,does not
Take the carb off and you will see the little rubber mounting on the fuel tank.I mean the connection between the carburator and the fuel tank. Shake a little bit the whole saw. If there is gasoline coming out on the rubber mounting than it means that the fuel tank respirator filter is dirty and air cannot exit the fuel tank so it will get gas out at the rubber mounting because the pressure inside. To solve your problem for the moment try to push out this little filter. Take off the gas tank cap and look inside , you will see an alloy piece with a hole in the middle. Use a very thin screwdriver or something similar and push it through this hole , this way you will push out the filter on the other side. Do not use a drill bit. I did it, bad idea.
Have fun !
Saw runs for 5 minutes and bogs out
This is sometimes caused by dirt in the gas tank. When the saw is off and being moved around the dirt settles to the bottom. The saw will start OK and rev up but after a while the dirt gets shaken up and sticks to the fuel filter in the tank. When enough dirt covers the filter the saw looses power or dies all together. Sometimes it will get enough gas to idle but not enough to run at high speed. With the tank half full, shake the saw to get all the dirt stired up and dump it out. Put a little gas in it and shake & dump it again. If you can fish the fuel line with the filter on it out, remove the filter and either replace it or blow it out. If this doesn't cure all your problems you may have leaks in the fuel line to the carb that are letting in more air than gas causing your power problems.
How do i start the saw
Hello. The steps are quite easy once you've done it a few times. When starting: pull the choke switch on, press the throttle lock as you squeeze the trigger (this locks the throttle into a half-on position), push in the decompression valve, and pull the cord. I recommend placing the unit on the ground and stepping in the trigger-guard area to stabilize it. Here's a link to the instruction manual for you reference - it shows the sequence with diagrams on pg 18 & 19. Hope this helps, if it does, please rate a four-thumbs up. Thank You.
