Ignition coil for the Homelite Super XL, XL-12, SXL and Old Blue chainsaws. Replaces Homelite part numbers 94605 and A94605S. THE CHECK TO RUN BEFORE ORDERING. Homelite used two different ignition makes across this family of saws, and the make is cast into the flywheel. Pull the starter housing and read the name off the flywheel before you order anything, because the two are not interchangeable. That one check is the whole fitment question on this part. WHY THIS PART EXISTS. The blue coils originally fitted to these saws were a known weak point, and the original manufacturer discontinued them. That left a lot of good saws with no factory coil available, which is why a reproduction is worth having. SETTING IT UP. The air gap between the coil legs and the flywheel magnets matters more than people expect. Set too wide, the spark goes weak, and a weak spark shows up as a saw that starts cold and fights you once it is hot, rather than as no spark at all. Hold the gap with a feeler gauge or a folded business card while you tighten the screws, with the magnets turned away, then turn the engine over by hand to be sure nothing contacts. BEFORE YOU REPLACE ANYTHING. Confirm the ignition is actually at fault. Pull the plug, ground it against the cylinder and crank the saw. A fouled plug, a cracked boot, a perished lead or a shorted kill switch all read like a dead coil and all cost a fraction of one.
- IGNITION COIL FOR THE HOMELITE SUPER XL FAMILY - Replaces Homelite part numbers 94605 and A94605S. Fits the Super XL, XL-12, SXL and the saw most people call Old Blue. This is the part for a saw that will not spark at all, or that starts cold and dies as soon as it warms up, which is the classic signature of a coil breaking down under heat.
- READ THE MAKE CAST INTO YOUR FLYWHEEL - THIS IS THE ONE CHECK THAT MATTERS - Homelite fitted two different ignition makes across this family and the name is cast into the flywheel itself. Pull the starter housing and read it before you order. It takes a minute and it is the difference between the right coil and a return.
- WHY THE ORIGINALS GAVE TROUBLE - The blue coils fitted to these saws were a known weak point and the original manufacturer stopped making them, which is why a saw worth keeping often has no factory part available. This is a reproduction built to replace them, and the reason it exists is that the supply dried up on a saw people did not want to give up on.
- SET THE AIR GAP ON ASSEMBLY - A coil mounted too far off the flywheel gives a weak spark, and weak spark reads as hard starting when hot rather than as no spark at all. Hold the gap with a feeler gauge or a folded business card while you snug the mounting screws, with the magnets turned away, then turn the engine over by hand to confirm nothing touches.
- RULE OUT THE CHEAP THINGS FIRST - A fouled plug, a cracked plug boot, a perished high tension lead or a shorted kill switch all read exactly like a dead coil. Ground the plug against the cylinder and crank it. An inline spark tester will tell you in a minute which side of the coil the fault is on, and it costs a fraction of this part.
