Hi, Most chainsaws use three mixes, which are 32:1, 40:1 or 50:1. Most are labeled somewhere on the saw. If you are unsure, use the 40:1 and watch the smoke, too much smoke use less mix, but don't run with too little, it is supposed to smoke some. If you see any oil coming from the exhaust it is too much and can't burn it all. Good Luck, hope this Fixsya!

Remove the spark plug and test for blue, snappy spark. If nothing, try a new plug set for 0.020" gap. If still nothing, remove the cover from the flywheel side to expose the ignition module. Remove the ignition switch wire from the module and try for spark again--if ok, check for a grounded ignition switch or the wire itself. If still nothing, replace the ignition module. Use a thin business card for a pole gap between the module and the flywheel magnets. Allow the module poles to contact the magnets, then tighten the screws. Rotate the flywheel to remove the card. If you got spark in the first test, then place some fuel mix in the plug hole and try to start. You should get several pops. If ok, then work on the fuel system. Check the fuel filter, air cleaner, and muffler for plugging. Check the fuel lines for decay or other damage. Make sure the carburetor fasteners are tight. If the machine is fairly old, you should check the condition of the lower chamber diaphragm in the carburetor--it may have become hard or cracked. Hope some of this helps!

Take the bar and chain off. Clean the engine area where the bar fits to and start the engine--oil should ooze out of the small port where you cleaned. If ok, clean the small drive-end oil passages that lead from the larger holes out to the chain groove on each side of the bar. They commonly fill with sawdust and dirt which plugs them. Clean the entire chain groove and check/oil the end sprocket if it has one. Reinstall the bar and chain, then start the engine and run the tip near some cardboard for a few moments--it should throw off a thin line of oil. Hope this helps!

What kind of saw. How old? New Spark Plug? How old is the gas inside it? Is the air filter dirty? When you try to start it does it turn easy or is it a little stubborn or won't turn at all?
