Question about Poulan PP4218AV 18" Chain Saw
Starts up fine. Idles great.. squeeze throttle, dies 3/4 way through.
Mine had the same problem. it got better after diluting my gas mixture. it is supposed to be 40 to one ratio. I added a little mor gas to the jug and it runs better now. Bottom line is the mixture has to be right on. Too rich will give you the problem you mentionned. not rich enough might burn out the engine.

You may have a weak fuel pump diaphram in the carb. It may be a partially pluged fuel line in the
tank. It may also be a pluged muffler. Good luck.

Engine stalls or RPM
fluctuates at idle up and down or dies near idle.
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
