Did you check the oil before you started mowing and is it now full of oil.

Try spraying some Gum Out carb cleaner in the throat of the carb. Could you have water in the fuel?

Just because it has a full tank don't mean it's getting to the Carb / engine intake ......start from there and work backwards

New fuel. Pulled line off above fuel pump just below carb. Steady stream of fuel coming from there. Checked compression. Left side has 140 and right side has 145. Engine has about 930 hours on it

Well , for an engine to run has to have
1 - Fuel
2- Compression
3- Fire
4- Timing
Go down the list and see what's missing ,
Did you happen to hit something ? it can shear the flywheel key a bit and that's all it takes for your timing to be off and it aint running for anyone ...
