Hi i have a homelite chain saw csp 3314 and is not been use for tow years ,i try to start but refuses to ,it has a good spark ,i don't know why is not starting?? any help i will apresiete.
Most often this is because the gas has "soured" - it breaks down into a varnish compound, which is easily recognized by a foul smell in the gas tank that does not smell like gas.
You need to drain all the old gas. Pull the spark plug (clean it also- using a new plug is even better!), pump the primer bulb, and then pull the cord twenty times or so with no plug in the engine to try and purge all the old fuel. Get as much as possible out of the fuel system- the primer bulb should only have a drop or two at most in it.
Next, put in fresh gas along with a little carb cleaner- mix a gallon of gas with half an ounce of carb cleaner, plus whatever amount of two stroke oil you normally mix per gallon. Put the plug back in. Press the primer bulb 3 times, set the choke, and try to start. Make sure that you can see fuel in the primer bulb.
Your chainsaw will probably fire on the first or second pull, but not run (if it does start and run, GREAT!) On the third pull, most often it will start....if not....
Pump the primer three more times, and try the starting procedure again, and hopefully it will start, possibly running rough for the first minute.
If you still cannot get it started, pull the plug, clean and dry it, and try again... it is best at this point if you have a brand new plug to use it instead.
If your saw will still not start and run steady, you probably have a "varnished carb" - buildup from the gas souring has clogged the needle valve/orifice, and the float may be stuck. You will need to service the carb.
Good Luck, and Thank You for using FixYa!
