Flooding 914

Post by orenjr »

I had an issue with my 914 flooding after shutting off warm engine. Stopped for 3-5 min and would not start.
Do any of you know
1 Why would this happen ?
2 What can I do to start again ?
3 What can I do to keep it from happening?
Thanks! Oren

Oren,
Call Ronnie Smith at South Ms. Light Aircraft. He is very good at helping resolve these type issues. He works on these engines every day, rebuilds them, resells them, teaches maintenance classes, represents for Rotax at the big fly-ins etc and is nice guy. He can normally can point you in the right direction after hearing the symptoms of the problem. His number 601-947-4953.
Take Care,

Have you checked your floats in the carbs? Rotax has had a problem with sinking float, which will flood the engine. I had a float problem on my 912 ULS.

I Did some research and found out that it might be vapor lock and not flooding.
I will call Ronnie or Dean at Lockwood on Monday.

I have a buddy with a 912 in a Kitfox. He bought it used. He has had problems on and off with the engine, especially when leveling off after takeoff from his private strip. I think the engine has quit on him three times. . . all in a position where he could make it back to his strip.

He has investigated coils, carb floats, etc. The original builder has run the carb bowl overflow lines into a tube that runs down the firewall and exited out the bottom. I am not for certain, but he talked with one of the guru's. . . .i think Ronnie Smith? When my buddy told him about how the overflow lines were plumbed, he was told to disconnect all that stuff and put the lines back to the original configuration where the lines are run inside the bail that holds the bowl on. His engine now runs perfectly.

Please read this!

Those are not overflow lines. They are the "pitot
tube" for the altitude compensating carbs.



It is the path for the atmosphere pressure to
balance the diaphragm for the required
fuel flow.

It is critical to not add tubing. If they are
extended to the bottom of the cowl, as
some have done in the past, it can create
a vacuum from the passing air & can
adversely effect carb & engine function.

There are many things that happen really fast when you are
flying an airplane. There is no sense in rushing any of the others.

I would much rather be looking down at the runway, than up at it.

It didn't seem so dramatic when I
posted this initially, but I can't
edit it now.

Sorry!
