Briggs ignition coil

kick back

The old Briggs and Stratton in my opinion are the best little engine by far easy to service and run even when abused.
Yes they can kick back and yes it is painfull, usually caused in mowers by hitting a brick or obstruction that shears or deforms the key in the keyway on the main shaft Knocking the timing out .
I like the idea of the file for fileling valve stems saves the cost of a new head gasket on an old engine.I would of cause grind the teeth of the one side to save the follower.
As for the OP If it is a Magnetron type coil? disconnect the kill switch spade and see if you have a spark.

Too big a valve gap = decompressor not working, cord snatched and thumb injured . Seen it happen, acquaintance ended up with his hand strapped up for a fortnight!
I joined this forum to benefit from the expertise and best practice of those who know far more about welding than I will ever know not how to bodge. It's a bit sad that others want to "rubbish" information given in good faith by someone who for the last 30 years has made a decent living selling and servicing small engines. - just saying!

Well I didn't mean to come on so strong, but a little bit of qualification with your statement would have saved that. I posted what has so far worked perfectly for me three times. My wife easily starts our mower and she isn't what you'd call sturdy.

know anything about robbin diesels ?

managed to tip the machene over and it got hold of it's own oil, lost most of it's compression now, worth takeing them apart to look and try fix or can it be safely said to be knackerd ?

I suppose that it's just possible that oil got above the piston while there was sill enough momentum in the engine to bend the valve push rods (if it is an ohv) or even bend the conrod or snap the camshaft but there's only one way to find out. Not too big a job to pull apart and will be interesting to know the answer.
Read that early model Renault Espaces had a low mounted air intake and that there were a few cases of them going into a few inches of flood water, swallowing a dose and wrecking the engine. Liquids don't compress!

Slightly off track
You know these little strimmers etc with the air mixture and speed screws that are recessed and splined so you can't adjust them.
Take the litttle barrel screw of an old spark plug put an hacksaw cut in it for a screw driver, its soft ally? and tap the other end on the adjuster screw and adjust to your hearts content.
well it work for me and saved me getting special tool

Well back to the orig. Thanks for the advice. Took the mag off and the faces were very rusty. Put it on the wire wheel and refitted using a piece of paper as a feeler gauge. Up she fired.
