Does anyone know of an aftermarket or other brand name ignition coil for a Stihl FS 76 trimmer? OEM Part Number is 4133-400-1301 and it fits models: BG 72, FG 72, FS 72/74/76, and HS 72/74/76. I'm trying to get out as cost effectively as possible. Also, if anyone knows of a service manual for this model I'd sure appreciate it or at least a list of the specs. and tolerances, etc.
Thanks

You might want to try this---
Remove the spark plug and also lubricate the cylinder wall, and make sure the clearance between the flywheel and coil is correct---app. 012. Proceed to spin the flywheel with an electric drill, at about 2,000 rpm, being sure rotation is in the right direction. C/C in most cases. Flywheel may have to be spun for a length of time but I had results within a few seconds from a DEAD coil. Be aware that you will most likely unscrew the flywheel nut. Best to have a variable speed drill and start slow and remove from nut when stopping to prevent shock.
These modern day coils are complicated because many change the engine timing and also limit the maximum rpm.
Good Luck--might work for you and it will cost nothing ;D ;D

Yes, but it doesn't always work. If the coil is burned up, of course it won't work. I think these coils (modules) have a microchip or triggering devise that sometimes gets lazy.
I work on small engines and have revived several.
