Make sure to use fresh fuel mixed at 40:1ratio. Pour a little fuel mix into the spark plug hole and try for start. If it pops a few times, look for fuel system problems. Check the fuel filter, air cleaner, and muffler for plugging. The carburetor may need internal cleaning and check the condition of the lower chamber diaphragm for flexibility, no holes, or cracks. If the saw if fitted with a primer bulb, make sure that it will fill with fuel when pumped several times. Hope this helps!

Starts up but in time it will not revup, it will drop off and will die


Check the air filter and if this does not solve the problem check the spark arrester screen in the muffler. Also check for a clogged fuel filter in the fuel tank.

I have a Toro Model 20070 Electric start Lawn mower. It will not start. I changed the plug and filter. I pulled the plug and there appears to be no spark. When I turned it over I saw no spark. I guess my...


check your mower for interlock switches that might interupt spark for safety reasons.

A chute switch or something like that. Check your owners manual for troubleshooting.

Unplug the keyswitch and try pull starting to rule out a bad switch.

If it still doesnt have spark you might need a new coil.

The coil is right under the recoil cover and are fairly cheap.

A set of hand tools and $30-50 for the part should do it.

Good luck and be careful.

Saw does not start


  • If the saw was left away for a few months with fuel in it then a gel forms in the carburettor. If this is the case the carburettor may need to be stripped down by a professional and the jets cleaned.
  • If this was not the case the following procedure should get it running assuming that the spark plug is sparking. Even if fuel was left in the saw it may still solve the problem if it's not too bad.
  1. Remove the spark plug from the saw. If you want to check that it's sparking push the plug back into the HT lead, Rest the spark end against a metal part of the saw and pull the start cord. Check that the plug is sparking while you're pulling it.
  2. Assuming that the spark is ok pour about 5ml, one teaspoonful, of fuel into the opening where the plug came out of.
  3. Dip the spark end of the plug in the fuel so the spark gap is wet and replace the plug in the saw
  4. Try to start the saw.
The fuel that you poured in will ignite and should start the saw. The procedure may have to be repeated 2 to 3 times. Don't be tempted to use more than the 5ml of fuel or you'll flood the saw.
I hope this solves your problem.

After starting and operating the chainsaw for a short time, it dies and I can't get it started again. Suggestions?


Engines require 3 things. Spark, compression and fuel. And chainsaw need 2-cycle oil mixed with the gas.

Assuming you have the right oil-gas mixture and a fresh batch of gas, and you didn't leave old gas in the saw all summer long since last November.

-Take off the dirty air filter and see if saw starts without filter. Do not run without putting in new filter.
-Check exhaust port for mud dobber home or screen clogged with carbon and dirt
-See if saw fires up after squirting WD-40 directly into carburetor
-Check gas line >>> pull gas line loose and see if gas flows out of tank to carburetor
-Take out spark plug > put finger over spark hole and pull cord >> do you feel suction that says you got compression?
-Put spark wire back on spark plug >>> hold spark plug so threads touch bare metal part of spark plug hole >>> pull starter cord and see if spark shows between plug and saw >>> suggest you not hold metal part of spark plug while pulling cord [you'll understand why]
-If spark plug shows spark, then your saw has spark ... so put in new plug and start fresh.

If your saw has compression, spark, and fuel it should start unless carburetor is gummed up because gas was left in tank.
Here is the final trick. Start the saw while spraying WD-40 directly into carburetor and see if you can keep it going with the WD-40. This might take a helper. If this does not work, then carburetor is bad or gas line is clogged at carburetor. Time to take it to the shop.

Try checking for spark when she won't start. I'll wager your ignition module quits when it gets good and warm. HTH

Wont start with new plug. I can smell gas, but none on plug


Check the start stop switch, sometimes they can get dirty causing the saw not to get spark. Also maybe check Your air cleaner. if it's clogged it may be flooding itself out?
