Don Maxwell's Hot Start Video

[M20S Driver]

I just saw this on a link from MAPA..

This is on a Lycoming engine. Is it the same on io-550?  

 

He makes it look so easy

the "mixture as a throttle" technique i have used some while flying, but I've never seen it while starting. Good stuff.

 

The first start is typical of a 30 minute turnaround. Notice it catches, then dies, stumbles, then runs badly until he gets it to 1500 RPM. This is the fuel starvation in the engine driven fuel pump, or air in the fuel lines under the cowl. A few seconds of boost pump, or starting it with the boost pump on will eliminate that dying.

Its how I learned to start the first Mooney I ever flew. It always worked for us.

Nothing new! It's a warm engine start as per POH.

Touch nothing except key and mixture. Throttle is already cracked in a little, (I leave it at approx. 1000 rpm) since previous shutdown.

Simply turn the key and watch it fire in a couple blades.

Be ready with mixture and modulate.

Works like a charm!

The Continental IO550 will vary for one reason...

The fuel line can be flushed with nice cool fuel to avoid sending vapor bubbles to the fuel injection system.

The reason is there is a return fuel line back to the fuel selector.

To use the return line, the IO550 uses the hot start procedure that begins with running the fuel pump with the mixture in the idle cut-off position... (Check your procedure, I'm doing this from fuzzy memory...)

What are the costs involved with adding a return line...$&#?

None of those are really "HOT" hot starts, even my IO 720 will start after 1-10 minutes. The real challenge is 20-40 minutes when the flow divider, the fuel servo, the fuel pump and fuel lines are burning hot.

On a Lycoming there is no provision for recirculating fuel like at Continental engine.
