combatpilot said: When you say bent the reed valve how did you do this. I found when the reed stop was bent to where it clamps out on the end like you did it held it to the plate pefectly without having to put a bend in it anyhow. Pressure will also help it seal.
I just put a very slight curve in it to match the curve of the seat. Just used my fingers. Now when I look at it side ways I see no light anywhere between the reed and the seat.
Just did a test comparing a 9mm venturi carb to an 8mm. It gained 85 rpm and 0.8 lb thrust. The 9 is the biggest carb I have. I assume you are happy with the idle on your 12.7mm carb???? What sort of RPM's do you get at idle?
