How stupid can one be?
My little bird was finally repaired, and ready for taxi test and perhaps a first modest hop.
After all, the nosewheel steering had not been fine adjusted, and worse: the prop setting had only been tested statically.
So I went to the airfield in high spirits, only to find myself unable to start the engine. Got a couple of friends to help, tried this, tried that, battery jump cables from my van, nothing would help: no sparks to be seen in the plugs.
Left the craft for a week, the battery sucking from a lent charger.
Yesterday: exact same phenomena. More friends came in, more twiddling with the electricity, still to no avail. Called in the local guru, still more twiddling. No good.
Finally someone observed that the throttle was wide open, where it should be fully closed for starting a cold 912.
Blushed, closed the throttle, pulled choke, magneto's on, shouted everybody off, turned the key, and VROOOOMMM it went!
There's an awful lot of people that I now owe one!
Anyone ever been more stupid than that?
PS: I did taxi round the field, but there was too much wind and too gusty too for even the slightest hop. Only some brave glider pilots took to the skies.

Oh the key thing... I go for a full dress-up only reluctantly but this time we were going to the Hamptons so there I was, decked out in appropriate summer wear, only to find that the keys were in my jeans pocket of course.
Fashion victim! I still hear my fellow travelers howling with laughter.
If I didn't have my head screwed on I'd have forgotten it at one time or other. Like my passport, money, glasses, license, papers I'm supposed to bring, bank card when I'm standing before the cash machine, you name it.

And I have had to ask my wife to meet me with the keys half-way to the airfield, twice.

Good article in the latest LAA magazine about the importance of doing checks EVERY time before starting the engine. Just think what might have happened if the engine had started with the throttle wide open.

Hence why its so important to use check lists and walkarounds

Yeah, enthusiasm can add a layer of stupid to any of us. I can't count how many times I've tried to start a plane with the mixture at ICO. The last, and most memorable time, was in Reykjavik, getting a checkout in a rental C172. There was no checklist in the plane, and for a C172, I really should not need one!
When the check pilot put in the mixture to help with my third start attempt (and to save his battery), he asked me: "you are a pilot arn't you?". He was serious, I had only told him I was, I had not proven it yet. "Yes", I humbly said, "and with 6200 hours, you'd think I could start a C172 from memory!". Everything went fine after that...
Now, every time I fly, I assure a 10 second stop and sanity check, at least once before takeoff - I think I have done everything, but am I sure? Am I rushing too much? It's quite illuminating what I find I have missed!

.
The Rotax is designed to only start at idle
But had a can of aether ("Start-Pilote" or such) been around, I might have been severely tempted - and the results might indeed have been disastrous. But be assured: the plane was heading to the open, nobody in front of it, brakes applied, and my other hand ready to cut the magneto's. I am not a permanent idiot, not yet at least.
I am now finding an acronym ("to start - pull all" or such) to help remember the right direction of the throttle.
@DAR: the 10-second habit seems a good idea, thanks!

Not much use if the list says "throttle to idle" and you firmly believe you have set it to idle.

Basically I'm saying to myself: "I think I am doing something stupid right now. Let's take some time and figure out what."
Usually I'll find nothing wrong, but every now and then I do find something wrong, which I would not have caught otherwise.

Anyone who does a check list on the basis of what he/she believes rather than what he/she sees or touches is in for a very rude awakening.
PS. I never claimed to be very bright.

I know a guy, one early morning did his pre-flight inspection, pulled the plane out, about to turn the key, only to realize the propeller was missing!
Tried to start a BE76 just after my checkride in the very same plane. It wouldn't go. A friend yelled to me - Mixture! That made the trick. Examiner was watching the show.
Another time flew a C182 for two hours to pick up some acquaintance for further transportation. 10 min from landing was informed by ATC that the runway was closed re-painting. Due to open some 8 hours later. Ooops…missed that little NOTAM.
So easy to make a fool out of yourself in this business

I removed the "Remove before Flight" off of both pitot tubes; but while taxiing to the runway my non-pilot passenger said: "is that yellow rubber supposed to be on that pipe"?
Oops, the inner tube (a piece of hose) of the pitot cover was stuck on the pitot tube; and it took a complete novice to catch me out!
Well done to the girl!
Oh yes, and why would my beast cruise so slow?
Because it helps if your get the flaps up after T.O!!
Nothing like it to give your ego a blow at the beginning of a long day of flying.

Picked it up from maintenance, completed all my thorough checks, would not start. Completed ALL checks again, still would not start. Called the engineer - plane wont start. Fine lot you are, confirming all my suspicions that the maintenance co were a bunch of overcharging cowboys.
Engineer walks over from hangar, looks in, and asks me to switch the fuel on. Try it he says, might start then.
I sat there
Also the keys, 100 mile round car trip with wife and kids. I naturally blamed her

That is complete rubbish, I have seen one start at full throttle and heard about another (which wrote off a brand new flexwing aircraft and nearly destroyed a portacabin).
The carb fitted to the 912 engines is designed so that "the choke only works when the throttle is set to idle". If the engine is warm and the float chambers are full it will start at any throttle setting. It always surprises me how long the engine stays "warm" for. I find that it happily starts without choke for several hours after stopping. Very rarely use the choke more than once on any day.
