Played around with it today and went through all the used coils I had laying around (3) and all did not make the engine fire!
The coils were in unknown condition but thinking the odds of 3 coils being bad were slim I figured maybe I missed the timing mark on the camshaft so pulled the engine to inspect and I did have the cam timing marks where they should be.
Going to have to get a new coil and see what happens.... if that dosent work I'll be out of ideas.... I seem to be having bad luck with ignition systems this year
On the B&S engine, the points are operated by the crankshaft, not the camshaft, so you would have spark even if the valve timing was wrong.
Is the top bearing surface of the block worn, allowing the gap on the coil to fluctuate? .....Can you "rock" the crankshaft in the block enough to affect the point gap?
Is the plug wire on the 291617 coil soldered on, or is it molded into the coil?
Flywheel magnets good & strong?
Points grounding out?
Replacement condenser bad?
Is the plunger sticking in the block as previously?
With the luck you've been having with coils, you need to invest in a coil tester.
What model B&S? ....6BH?
