Default Re: Opti 2

Well gents, with my newly rebuilt engine and freshly rebuilt and adjusted carb I can say happily that the opti is working just fine in my engine I have a lovely chocolate brown plug to show for it. It works just fine on the NT carb, you just need to play with the needle and perhaps jetting until it stops running rich. The addition of an expansion chamber leaned it out a bit for me, as expected Well not leaned out, jut more fuel used Peace
