The first two took me right back to 1965 and starting the F4F @ my A&P school, except our airplane had been 'modified' and 'improved upon' by previous classes so switches were all over that cockpit and you had to be like an octopus on speed to hit this switch while crossing over to push that to crank this, and just as that old 1830 started barkin' you could count on the student doing fire guard to stick his head over the inboard left wing root and shout 'FIRE!!! KEEP IT CRANKIN"

and it wasn't the engine, it was the dirt under the airplane burning from years and years of oil and gas leaking and saturating the ground, after a minute or two the prop blast would blow the fire out.
All part of the fun of being 17, the airplane got traded to the Navy for a VERY VERY old BELL H-13 on castering wheels not skids.
