You will need to bench run the engine and see how it works? Some people have been successful.

The best pleaures in life are the more simple ones...

Meaning no fuel pumps and regulators if you don't really need them. If you need them, then, your are going to need to pay the price if you are going to listen to the music?

For years this has been coming up about factory fuel regulators on model engines.

Enjoy,
