RE: Fuel System Question - Saito Twin
Hello; Your problem is using the oil drain port to pressurise your fuel tank. Try setting it all up with no pressure at all and see what you get. I have a 100 twin that pressureises the tank with a fitting on one of the exhaust pipes. Due to the timing of the engines and the pressure pulse occuring once per rotation, one cylinder won't be getting the same pressure as the other. I had to use two tanks to get my 100 to carberate properly.
