Engine Will Turn But Not Start

Engine Will Turn But Not Start
Afternoon All,
I recently got back back from two days of road racing. The motor became more difficult to start until it would no longer catch. I brought it home and changed the plugs, it has fuel and spark. The compression in both rotors is 45 psi with the top plug in and the tester in the lower holes. I can smell fuel out the tail pipe as well as thru the open spark plug rotor hole and I have spark in all the plugs.
Any ideas? It ran flawlessly both days until it it would only crank and not catch....

air, fuel, spark, compression
EDIT: did you try the un- flooding procedures? if you know it's getting air, you smell gas, you're getting spark, and the engine isn't blown it should fire.

While compression testing a cold engine doesn't produce "exact" results.... If you are only seeing 45 PSI and you did the test properly, your engine is damaged.
