Hot Start with E-Mags?
I recently purchased an RV 7A. It has fueL injection, one conventional and one E-mag. The other day someone suggested I never use the tried-and-true hot-start method to start the plane; that it is harmful to the E-mag.
Thoughts? Thanks, sle |
Did he/she offer any reason or logic to back up his suggestion?
To harm it?!?!??!?!? |
I have an E Mag and magneto on my RV6 with fuel injection. My hot starts I always start at idle cut off and the throttle open a little. This is the same way I started it with 2 mags.

Plus 1 on that.....
Starts perfectly, however...... If you have stopped for say 10 minutes, when you start again, there may be some stumbling and missing for a few minutes - just vapour in the lines as the Lycoming doesn't have a return loop system. |
Wouldn't it be logical to expect Emagair to note that a particular hot start technique is a problem? Yet they don't. Call Emagair and ask them. I would bet that your "source" at the airport also thinks LOP is a bad idea

Must research the source and use judgement in accepting advice like this. Many suggest that walking under a ladder will create adverse consequences.
I remember my transition training CFI adamantely suggesting that I prime my carb'ed engine by pumping the throttle. Most know that when this is done with the engine not spinning, it loads the FAB with raw fuel and creates a serious risk of engine fire if you get a backfire. While the CFI had no idea how an engine worked, he had heard this so many times that he assumed it had to be correct. How could it be wrong when every car produced before 1980 was started this way?

My technique
FWIW...
Lyc IO-360 M1B, one slick, one Pmag. Hot start technique..... Boost pump....ON Throttle.........WIDE OPEN Mixture..........FULL RICH (2-3 SECONDS) Mixture..........ICO Throttle.........CLOSED Boost pump...OFF Throttle.........1/2 OPEN Starter...........ENGAGE Mixture..........SLOWLY ADVANCE AS IT BEGINS FIRING Throttle..........REDUCE TO IDLE This works for me every single time. YMMV |
Thnx Steve/All. Steve’s method sounds like the best path. The person who warned me against it had no maligned intent and is not, to the best of my knowledge, superstitious. Perhaps he is, like me, still trying to learn about non-cert aircraft’s idiosyncrasies.

Steve forgot to turn the mags on:D
