no/low spark...is it the coil ?

[dasboat]

Hi, just finished installing new carb kit/lines/spark plug and ready to start the saw...getting low/no spark and thinking its a coil issue. Cleaned it up and no change. Want to replace ignition coil and need the part #.  Guidance appreciated - Thanks

You'll have to look at the type of your flywheel and see what brand of ignition you have. It could be Phelon or Wico/Prestolite; parts don't interchange. This IPL should help: www.leonschainsawpartsandrepair.com/uploads/3/9/7/9/39792537/homelite_xl-1_chainsaw_ipl_24323t__revision_5_.pdf

FWIW, the condenser could be the problem as well...it would be cheaper to replace than the coil.

Suggest removing the module from the saw, inspecting and testing the ground and high tension lead connections,
then baking the assembly at a low temperature for several hours...Often it can be revived.

Crap, I misread that danged Terry serial number as 1978 instead of 1982...good catch!

Its a blue Prestolite coil, solid state. Reads 5.46 ohms...does that mean it a good coil or failing coil ?

They can't not be tested with a ohm meter to determine if they are bad. Your best option is to bake it to try to revive it. ( see link) They are also not called coils, they are a module,
