C. High-speed Adjustment:
The high-speed rpm and transition performance is adjusted with the high-speed
“H” needle valve. When adjusting, turn the screw about 1/8 of a turn each time.
The position of the “H” needle will vary according to air temperature and field
elevation. If your engine is running smoothly, then do not adjust this needle valve.
Follow the recommended procedures if any of the following happens:
Problem:
1.
Engine stops at full throttle.
2.
Engine hesitates when accelerated rapidly.
3.
The engine will not come up to full rpm at full throttle.
Solution:
Your high-speed needle valve “H” is too lean. Open it 1/8 turn and try again.
Problem:
1.
Your engine does not reach full rpm.
2.
Carbon build-ups appear consistently on your spark plug.
Solution:
Your high-speed needle valve “H” is too rich. Close it 1/8 turn and try again.
