Default Re: Higher flow petcock?

My motor is a 150 4-stroke and it eats up the gas pretty quick.. But yeah around an hour to hour of runtime or slightly more. The petcock is gutted, not even a spring inside- it's epoxied shut. In tank screen removed long ago. Inline filter. Tested it all with the stock engine tank (think side of water pump engine) and I don't get the high rpm fuel flow problem. To drain a small amount of fuel takes a good five to ten minutes even with the cap off.

I went to the hardware store after reading the replies but could not find a suitable valve. Instead I found an inline shutoff valve made of plastic that I will try; as for the petcock I'm going to drill it out to 5/32".
