Hi
Thanks for this.
I guess my question to you guys is ,Why did I see the secondaries opening right up before tune and now they don't.
Is that because the tune has increased the efficiency and burn of the fuel?
In my line of thought 'the velocity of air/fuel entering the primaries wouldn't have changed,thus how would the jetting and tune have lowered the velocity enough to now not allow enough vacuum in the secondary diaphragm to open them fully ??
The only explanation I can come up with ,Is that because there is now more fuel being mixed there is less air being dragged in.
Is this correct

Thanks
