Wire Harness 530057943

Coil and harness are simple. All my wires were slightly damaged so I changed everything. It wouldn\'t start on ether and now it starts pretty good on fuel if my elbow is up to it. Used an old business card to set the coil gap. Less is best as long as it doesn\'t rub. (@ 0.010) The air filter and housing were only changed because the housi ...

I bought it as a $70 refurb at Home Depot and probably spent that fixing it after the fuel lines rotted out. It\'s a Poulan P4018WT. Guess you could say it runs better than when it was new. Spark gap is about 0.020. or .5MM (a mm = 0.040) These don\'t have a lot of ignition voltage so keep the gap close. It isn\'t your car. Do yourself a favor and buy the canned pre-mixed fuel. Ethanol will rot the lines out and destroy the carb. If you don\'t put a lot of hours on a saw it isn\'t worth finding the \"real\" gas and mixing it. Since Poulan won\'t give RPM limits I set it for 9k under load. It sounds about right.

Note that when reattaching the black wire to the start stop switch, use a flathead screwdriver to gently move the metal connector plate nearest to the red switch back, then insert the end into the opening and release the metal plate.
