Mower running very rich

[Mohawk]

Thanks guys. I checked the needle when I had it out. It’s still sealing the inlet (couldn’t blow through when sealed) and is still soft seating. Motor does keep running and runs smoother for a few seconds when I turn off engine. I take it this is because the fuel solenoid closes cutting off fuel and the mix goes right for a few seconds.
The new coils have a very strong spark. Fuel is new hasn’t been sitting. Thanks. I’m going to get a mechanic to check. Will let you know his findings if any. Cheers guys. Thanks again.

Only 2 reasons for an engine to run rich
1) float bowl fuel level too high
2) fuel jets too big ( or missing )
Does your engine have a single barrel or twin barrel carb ?
On the latter ones the idle jets are different sizes and if you mix them up, one side will run rich & the other lean
