Hi Aquaflight and XJet,

Can you post pictures of what you did?

From your descriptions, I think you:
Eliminated the airleaks (if you had any),
Drilled the brass insert at the fuel intake for better alignment (as described earlier)
And filed the spray bar a little - could you mic it and give us the new length - a picture of the measurement end point location would be good.

Thanks for taking the time to analyze the problem and do the testing.

Fly4Fun,
