Two prong solid state electronic ignition module for Homelite chainsaws. Replaces the breaker points and the condenser, keeping your original coil. Instructions are included. The module is a transistorised switch that wires in where the points were, inside the flywheel. Rather than a mechanical contact opening and closing on a rubbing block, it switches the coil's primary circuit electronically. Nothing to file, nothing to gap, nothing to wear. Fits Homelite saws that still run breaker points - Super XL, SXL, Super XL Automatic, SXL-AO and XL-12. The test is what is under the flywheel rather than the badge on the saw: if it has points, this replaces them. If it already has a factory electronic module, it does not need this. Two hard limits, both quick to check before you order: It will not work on a flywheel with three magnets. Count them. It will not work on battery ignition. The module itself has two prongs, and it suits both two-leg and three-leg coils on single-cylinder engines - the legs are the laminations on the coil, not the prongs on the module, and those two get confused, and it replaces the older Wico, Prestolite and Phelon points arrangements as well. Why people fit them: the rubbing block on a set of points wears down, the gap closes, and the ignition timing walks out with it. That is why a saw that started on the second pull last season fights you this season. Points also gum up and corrode on a saw that has been standing through a winter. A solid state module holds its switching point permanently and is sealed against damp. And what it will not do, said plainly: it will not add power, raise RPM or change the ignition timing, which on these saws is fixed by the flywheel and is not adjustable. Before you order anything, confirm the ignition is the problem. Pull the plug, ground it against the cylinder and crank the saw. No spark, with sound kill-switch wiring, is what sends you here. Weak running, hard starting when hot, or a saw that dies under load is at least as likely to be fuel, an air leak or compression. Coil, flywheel, spark plug and plug lead are not included.
- TWO PRONG SOLID STATE MODULE - Replaces the points and the condenser, keeping your original coil. Two prongs on the module itself. Nothing to file, nothing to gap, nothing to wear out. Instructions are included.
- FITS HOMELITE SAWS THAT STILL RUN BREAKER POINTS - Super XL, SXL, Super XL Automatic, SXL-AO and XL-12. The test is not the model badge, it is what is under the flywheel. Points means this is your part. A saw that already left the factory with an electronic module does not need it.
- WILL NOT WORK ON A THREE MAGNET FLYWHEEL - That is the hard limit and it takes ten seconds to check. Count the magnets in your flywheel before ordering. It also will not work on battery ignition. The module is two prong and suits both two-leg and three-leg coils - those are the laminations on the coil, not the prongs on the module, and the two get confused.
- WHY PEOPLE FIT THESE - The points rubbing block wears, the gap closes and the ignition timing drifts with it, which is why a saw that started easily last season fights you this one. Points also gum and corrode on a saw that has been standing. A solid state module holds its switching point permanently and is sealed against damp, so a saw that has sat all winter starts the way it did in June.
- WHAT IT WILL NOT DO - It will not add power, raise RPM or change the timing, which on these saws is fixed by the flywheel and is not adjustable. Before ordering, ground the plug against the cylinder and crank it: no spark with sound kill-switch wiring is what sends you here. Coil, flywheel, plug and plug lead are not included.
