Steve,

I fly a Commander 112 with a 200HP Lycoming IO-360; the angle valve = engine. The hot start technique I was taught has worked reliably = and it=20 doesn't matter if the engine has been shut down for a couple of hours or = just a=20 couple of minutes. My hot start checklist goes like this:

Mixture control to full lean

Prop control full forward

Throttle full open

Don't use the boost pump

Crank the engine (mags and starter are all on the same key = switch)

When the engine catches quickly push the mixture most, or = all, of the=20 way to full rich

Immediately pull the throttle back to idle

Make final mixture adjustment (I always leave it a bit lean for = ground=20 operation to avoid plug fouling)

With a little practice I was able to get the hang of pushing in the = mixture=20 and pulling back the throttle without running up excessive RPMs. = Using=20 this technique the engine has always fired up after 2 or 3 = revolutions.
