16"chainto fit saw model

well you can do what most people do.and i mean everyone does at some point in time chainsaw,weed trimmer,lawn mower.ect. just choke it out eventually it will die.done it many times myself.and still do sometimes lol...now I work on them for a livin this will get u byfor the moment .untill u can get a switch.

Don't use stabil. Use a modern synthetic saw oil (50:1 fuel to oil ratio) available at home centers, hardware stores, and saw dealers. Mix the oil and fuel in it's own container and be sure to shake the container thoroughly just before filling the tank each time to prevent oil starvation. If it becomes apparent that the carburetor adjustments are wrong, you will need to see your dealer for adjustment. Good luck!

Take the spark plug out--does it pull smoothly now? If not, the pull cord may be the wrong size or it is damaged and/or doesn't rewind correctly. Does the machine have a compression release? If so, it may be plugged with carbon. With the spark plug out, pull the engine through several times briskly with the throttle open and the choke off to expel any excess fuel from the crankcase. Hope some of this helps!

appears to be a 55 cc motor

ProMac 850 is 82cc capacity motor & Fuel mix is 25:1 - especially now that we only have unleaded... best to use BP Ultra 98 octane as these saws were designed to run on Super leaded fuel. I used to own a 797 Super (123cc motor)
