Remedy:
1. For about 1 to 2 minutes, or until the engine settles,
run at a speed of 1800 to 2000 RPM. Oil and cylinder
head temperatures must stay within limits.
2. Pull throttle back to IDLE to confirm smooth running.
3. Set throttle to 1200 RPM and mixture for taxiing, i.e.,
use mixture control lever to set the maximum RPM
attainable.
4. Immediately before the take-off run set the mixture for
take-off, apply full throttle and hold this position for
10 seconds.
NOTE
Vapor lock can be avoided if the engine is run at speeds of
1800 RPM or more. This results in lower fuel temperatures.
