That is the question, is it nobler to suffer the headaches of the 3rd line running from the muffler to the tank or to plug it off and just deal with the typical 2 line setup.

What would be the advantages of a pressurized system?

if pressurize system is not used, would it be necessary to have a pump for larger four-stroke motors?

I have a new Enya 1.55 4-stoker that doesn't seem happy with a pressurized system ... and it is finicky to set the carb to run at hi RPM ... only seems like a 4 click window from rich to lean

Suggestions and feed back welcomed. Advice from anyone except my dad is appreciated .... Joking dad .... NOT!
