Qualcuno sa' la regolazione della carburazione del motore nuovo? (numero di giri delle viti minimo medi e alti) Grazie x l'aiuto.

LOW SPEED ADJUSTMENT

1. Open the low speed needle to 1 turns from fully closed position.
2. The low speed needle valve should be set after the high speed needle
valve has been adjusted. Close the throttle gradually to a idle
(approximately 2500rpm). Let it idle for 20 to 30 seconds and then
slowly advance the throttle. The adjustment is satisfactory at low speed
if transition is smooth at this time.
3. If the engine is running rough on idle, the low speed mixture is rich.
If the engine starts to speed up and dies on idle or starts to detonate,
when advancing the throttle, the mixture is lean. Turn the low speed
needle valve clockwise to richen and counterclockwise for a leaner
mixture (note that the direction of the low speed needle valve is
opposite the high speed needle valve). Adjustments to the low speed
needle valve should be 1/8 to 1/4 of a turn increment at a time to
achieve smooth throttle response.

Tratto dal manuale, quindi per la vite del minimo/regimi intermedi un giro dal tutto chiuso (DA QUI iniziano le regolazioni).

Regola prima il regime massimo:

HIGH SPEED ADJUSTMENT

1. Adjustment of high speed is done by the carburetor needle valve.When
the needle valve is turned clockwise, the mixture is leaner.When it is
turned counterclockwise, the mixture is richer. A good starting position
for the high speed needle valve is 2 1/2 turns open from the fully
closed position.2. When the engine is started, open the throttle gradually. Next, find the
peak position (highest RPM) by adjusting the needle valve. Then the
needle valve should be opened approximately 1/8 of a turn from full
RPM to achieve best performance. The engine may stop if the throttle
is opened to full immediately after starting. Wait until the engine
temperature rises and then open the throttle slowly .
3. For flying, it is advisable to use a slightly richer mixture setting. By
using a richer mixture, the engine temperature is maintained and RPM
stability improves.

Quindi vai in moto con 2,5 giri dal tutto chiuso e poi, contagiri in mano, smagrisci fino ad ottenere il peak: a questo punto ingrassa di un ottavo di giro e vai in volo
