Robert,

I copied my input from an older thread and changed what was necessary.

Verify your fuel lines are as short as possible, but the clunk still reaches within 1/8" off the rear of the tank. It must be insulated from direct contact with any part of the airframe, by 1/4" foam latex, to prevent vibration and foaming.

Verify the tank centerline is within 3/8" above, or below the carburettor spray-bar.

To adjust the engine, start with a rich main needle setting and with the idle disk set in the middle.

Set the throttle to full speed and lift the plane's nose straight up.
It is preferable that someone will hold the plane firmly, while you adjust.

Close the needle gradually until closing further doesn't add speed, or causes a loss thereof. Then open the needle back until speed is 100-150 RPM below that maximum. It is imperative that this is done with the nose straight up, to simulate the situation that is most difficult for fuel draw. That would do for now.

Now set the plane on its landing gear and close the throttle to idle position (about 1mm open).
Listen to the engine carefully. If it sags gradually, it is too rich. You should turn the idle disk to the lean direction, about a click. This adjustment method is very sensitive. The entire adjustment range is about 3/8".
Advance the throttle gradually to full for a few seconds, reduce back to idle and listen again.
Repeat, until the engine runs at a stable idle speed.

If, on the other hand, the engine gradually speeds up at idle, it is too lean. Do the exact opposite of the previous paragraph (turning the idle disk to the rich direction).

From this baseline, check transition from idle to full power.
After running the engine at full speed for a few seconds, close the throttle to idle and keep it there for about 30 seconds.
Now open the throttle rapidly.

If the engine immediately accelerates, you are done.

If it sputters fuel before eventually speeding up, or dying, it is still too rich, lean the disk very little and try again.
If it hesitates (coughs...) before eventually speeding up, or dying, it is too lean, richen the disk very little and try again.

After you are done with the idle adjustment, re-check the main needle adjustment.
