I am looking for a solid state conversion magneto to replace a conventional ignition on a tecumseh Engine That Requires a 30561B magneto that is discontinued.

SOURCE: 4 hp Briggs Horizontal engine

On your flywheel there should be 2 holes threaded on the top area & the retaining nut in the centre.
remove the centre nut completely, then get a flat piece of steel bar (about 6" long x 1/2" thick x 11/2" wide) drill 2 holes (clearance holes) at the same distance as the ones on the flywheel.
then drill one in the centre about 1/4" dia.
Get two bolts that will fit into the 2 threaded holes & pass then through your newly drilled bar.
Place a ball bearing on the centre hole & tighten your 2 bolts inwards.
When they both start to get tight tap the flywheel with a hammer & tighten futher on the bolts.
The flywheel should now come loose.

Check that the gap between the flywheel magnet and the module is correct, take the kill wire off the module, hook up a spark tester to the output of the module (spark plug removed), spin the flywheel - No spark means that the module is bad.

Rank this answer please,

Not the solid state ignition. If this were the problem the engine wouldn't start at all. There is some adjustment needed to the carb but without more info, I'm not sure what.

SOURCE: my tecumseh engine has no spark

There is a shut down wire, This wire is grounded some where along the route. Look at the coil for this wire, it shorts the coil to ground so no spark can get out to the plug.
