The best blades are made of marbain steel. They are OEM on brands like Ferris Scag Grasshopper commercial JD and the like.

As others have said service alone if a one man shop won't pay the bills. Dealerships make their real money on equipment sales and service makes up a small part of their business. I run a shop with almost zero overheadh and make decent money but i have a comfortable retirement income also. I...
Last grasp at the straws.
I believe the engine has an external coil. If so try this. Disconnect the points wire from the coil. Connect an ohm meter to the wire from the points and to ground. Slowly turm the engine and see where the points open and where the flywheel magnets are in relation to...
Have you compared a 36 grit flap disk to a grinding wheel?

A 36 grit flap wheel is nowhere as nice as...
A 36 grit flap wheel takes metal off FAST without overheating.
I have a Bradley S105 grinder that i don't use any more. Really only works on flat blades and takes way longer than the angle grinder and flap wheel. Blades don't need to be perfectly balanced or razor sharp. Mow with razor sharp...
If the magneto assy wasn't moved that's good. Moving the mag/coil assy adjusts the engine timing but the points gap is critical to timing the magnets to the coil.
"I can feel the spark when holding the plug wire and spinning the flywheel by hand"
Sounds like the points are slightly out of time with the magnets. Try opening the points gsp a couple thou. If that doesn't help then close a couple thou.
Since it holds the angle i can very quickly sharpen the dullest blade to good professional edge in less than a minute. I run a shop and time is money. I have tried a few different sharpeners and the all american is the best bang for the buck for my small shop. A Burr King would be nice but can't...
I use an All American sharpener.

And 36 grit flap wheel. Takes less than a minute for even the worst blades. Blade off the mower $5. I don't straighten blades.
