of cold weather, engines and starters ( C-152)

Starter: 30-seconds maximum, then stop. You can do this three times. After that, stop and wait at least 3 minutes. Otherwise it gets too hot and burns up.

POH: (if flooded)
set mixture to idle-cutoff, throttle to full, run starter a couple of times. Then stop. Attempt restart without priming.

POH Cold-weather:
Ignition switch: OFF
Throttle--Closed
Mixture-Idle Cut-off
Parking brake set (or qualified person at controls)
Prime 3 strokes
Propeller--PULL through by hand several revolutions
Mixture--rich
Throttle OPEN 1/2 to 3/4 inch
Prime 2 to 4 strokes depending on temp
Primer--RECHARGE FOR PRIMING after engine start
Propeller Area--CLEAR
Master Switch-ON
Ignition Switch--START (release when engine starts)
Carb Heat ON
Prime --AS REQUIRED UNTIL ENGINE RUNS SMOOTHLY
Throttle--Adjust for 1200 to 1500 RPM for approximately one minute after which the RPM can be lowered to 1000 or less
Carb Heat --OFF
Oil Pressure--Check
Primer--LOCK


Cold-weather starting from an "old country boy":
10 or 20 pumps of the primer
get out of the plane
turn the prop thru 4 turns
preflight
prime again and it should start
(the gas is not vaporizing, just sitting there in a puddle)

checkride prep

Plan a one-way trip to Champaign, Illinois. Figure Peyton at 150 lb. Start over Clark County airport. Have a number of close checkpoints. Figure on short-field takeoffs and landings. Weather is not good tomorrow. Call tomorrow night to try to set a date and time.
