Comanche How to Start.

Filed away in my "plane manuals" folder inside my MSFS Toolbar on the Windows Taskbar. (I had to edit windows register to regain the Toolbars feature in the Windows 11 taskbar). Windows 7 thru 10 had Toolbars enabled by default.

5:40 really cold weather starts.

There used to be JC Whitney car parts catalogues which sold electric rods which replace the dipstick on cars for very cold morning starts on automobiles. Multigrade oils like 5-30 put an end to them.

All Lycomings are pretty much the same:

Mixture rich, carb heat cold, master on, fuel pump on, prop forward (if you’ve got a blue lever), crack the throttle, engage starter, throttle to 1,000 RPM, check oil pressure, lean the mixture, and voilard.

So you think the advice given in the video is wrong,, and you are right??

I get the feeling you’re pretty non-confrontational. I could be wrong though. And if you pay attention he does exactly what I said. Also depends on whether you have a push-button starter like the 60’s planes or a key starter. That changes how you engage the mags.

Simple, press the E key!

He turns on the fuel pump, sees pressure rise, and turns it back off before engaging the starter, so he won't flood the engine. That isn't what  you said..

It's in the manual:

Quote

Starting
It is not necessary to turn the electric fuel pump on for starting. However,
it is important that before starting, proper operation of the electrical fuel
pump is checked as the main engine-driven fuel pump will not be run-
ning. Once a fuel pressure indication from the electrical pump has been
verified, it should be switched off again. This is so that operation of the
engine-driven fuel pump can be checked independently too, without the
electrical pump running.

I am guessing that Bob could give you a pretty good argument about this statement…

I just like listening to people that are knowledgeable.

I’m sorry if I took your comment the wrong way, Bob. I think the difference is he has an engine analyzer, which gives you a lot more information, whereas I don’t. I also kind of paraphrased my process. This is my stock process, and it will vary depending on whether the plane has a pushbutton start or key start:

(Fuel on proper tank). Rotating beacon on, mixture rich, carb heat cold, master switch on, fuel pump on, (magnetos on left - older plane), prime as needed, engage starter, good engine start: magnetos to both, throttle 1,000 RPM, check oil pressure, fuel pump off, check fuel pressure. Then avionics master or radios, depending on the equipment. There are slight variations on it depending on the plane, but that process will start any Lycoming in a pinch.

Exactly the way I start my RV-9A (Lycoming O-320) Substitute NAV lights for rotating beacon.

There are two types of engine. One sthat hard to start in winter and ones that hard to start in the summer LOL Another cool vid from Scot. Also idle check is great explanation what to look for!

I’m not sure exactly what he’s doing there or why, to my knowledge you flood the carb by overpriming, not not running the fuel pump. Maybe this isn’t a carbeurated engine? But that would be an upgraded engine for sure. I can’t really say on this point.
