You can try a decarbon treatment in order to gain back some compression. It's a long-shot but it should help the situation. Some people choose to have their injectors sent out to be cleaned, this will also help. Your cheapest and easiest solution to your problem (although some call this a "band-aid" solution) is installing a fuel cut switch. Basically you start cranking the car with the fuel off and soon as the engine starts to catch you turn the fuel back on before it stalls.

Be aware that the most likely reason your engine is flooding in the first place is because it has low compression. The fuel injection system in the FC assumes that the engine has "x" amount of compression and gives it "x" amount of fuel. When enough compression is lost the computer is still giving it the same amount of fuel, causing a "flooded" condition.

The easiest way to raise compression in a worn engine is to rebuild it with fresh parts. This usually costs around 1,000 to do it yourself and 2,000 to have someone else to it.

The cheapest way to gain compression is to perform a carbon treatment. There are many ways to do this, many of which can be found by performing a simple forum search. Realize that gains in compression will me minimal at best and will likely not be the solution to your problem.

Would redlining really help with the carbon?

Pour thick oil in the plug holes.

I floor mine while cranking, this helps it a ton by giving it more air. If your compression is low enough, this won't help enough though, and it's time for a rebuild.
