Unflood engine

Re: Unflood engine

Please forgive the hijack...

Danny, the guy from the Twilight Zone was not Ron Seward, it was Rod Serling. I can't imagine any child of the Cold War not knowing that

Your website does indeed have an interesting story to tell, but IMHO your story should be told with better spelling, grammar, and punctuation.

The better it is written, the more effect it will have... because the way it is now someone can (wrongfully) take a shot at your entire credibility by pointing out that the quality of your writing does not seem commensurate with the level of professional achievements you have reached in your life thus far. if I were a NASA lawyer that's the first tactic I'd be using to take you out in terms of PR.

If the website content was formatted differently, written better, and had more data, perhaps you can get NASA to raise their offer to a higher number!

Thanks for the feed back. I fixed the problem on Rod Serling.

And I claim to be an engineer, not a writer I admit to being a very bad proof reader. I know the rules of grammar and punctuation, I just have a hard time seeing them in my own work. Feel free to point out any other errors you see, but send them private or to [email protected].

Re: Unflood engine

Acquaintance of mine, AI and instructor, hand propped a champ that he knew (at least everyone else, including me knew) had a mag switch problem, with a non-pilot sweetie IN THE PLANE, and it took off across the parking lot, with passenger, and ate another airplane. The mag switch was off.

Happens all the time; just another item of many that make me constantly question our species' sanity.

As I remember he always insisted that turning it over backwards would not clear the flooding condition.

PS: If there is just one piece of advice this old dude would give to less experienced guys, when it comes to dealing with airplanes or any dangerous device, it would be this: Always keep as many aces up your sleeve as possible. Like; tie it down, turn it backwards, check your mag switch regularly. I make mistakes, and I figure if I fly long enough mother nature is probably going to stomp me flat at some point, but I'm going to put as much armour between me an her as I find practical to put that event off as long as possible.

Re: Unflood engine

Where should the throttle be when back blading? I don't want to put it full open if I don't need to. Even with the mags off and turning over backwards, I don't like the idea of full throttle.

Re: Unflood engine

I love this stuff. The Taylorcraft Owners Manual says to "open the throttle wide and pull the prop through backwards a few times." The Taylorcraft Service Manual says "the switch is turned off, the throttle is opened all the way and the prop pulled through several times in the normal direction of rotation. It is a common misconception that to rotate the prop backwards clears the engine. There is no basis for this thinking." I still pull it through backwards.

Re: Unflood engine

Ok, here's the QUESTION. When the engine is turned over backwards is the air actually pumped in the reverse direction thru the engine--that is from the exhaust back out the intake and thru the carb? Seems to me that is the only way it would have any effect when proping backwards. I know it works, so I have always assumed so, but I never checked it to see if that is what is happening.

I could dig up up my information on cam timing that I was looking over when considering what cam to put in my Camaro last year.

I could probably dope it out without the reference, but it makes my head hurt.

Any commments, anyone curious?

Re: Unflood engine

The reason I always pulled the engine through backwards
was one .......That is what the ole guys said to do ........
two ......hopefully the engine won't fire and start with the
reverse timing. Nothing like a engine starting half throttle to
get you undivided attention while hand propping !

Re: Unflood engine

to Marty's defense here...he did not say to start with the throttle wide open,reread it.
you advance the throttle to wide open at the time the mag switch is turned off.
and he said when he restarts it the throttle is cracked.
as for my technique I do it just as the army manuel says for the l2 and it works great.
turn the switch on ..throttle closed and go for it ,for hot engine.

Yes that is exactly what happens. The engine is a big air pump and it will pump air backwards if it is turned backwards.

Re: Unflood engine

It works pulling backwards 4 to 6 blandes with the throttle about 1/2 open.
Have done it many times with the old case mags. on the plane.
Doesn't flood much with the new mags.
Have had the old plane since 1982.
