Jumping in on the end of another persons thread is not a good idea because we hvae very little to work with and will be confused between the different mowers
So start off by telling us what engine is in your mower.
The brand , the model & serial numbers so we can feed you useful information.

diagnosing your problem is really difficult because you have randomly changed out parts any of which could be causing the problem.

in the mean time start by determining if the coils are actually working.
Assuming it is a std magneto ignition ( which we do not know yet ) , pull the blower housing off then remove the wires from the coils.
Crank the engine & check for sparks.
Tell us what you find and in particular how many small wires are connected to your coils.
