Hi Folks,



I have a 912UL installed in a Zenith 601HD. Terrific little engine.



I've read in a couple of places that 912 engines are not terribly

susceptible to carb icing, but operating on the principle of "better safe

than sorry", I've been thinking of adding it. I wondered if anyone has any

experience with the unit shown at

http://www.ultralightnews.ca/bing/carbheater.htm.  Seems like a simple

solution.



Along the same lines...anyone heard much about the 912XTRA piston conversion

kits - good or bad?

Tim,



Rotax says that using non approved piston will void the warranty.

The one shown on www.ultralight is the mark 1 version sold

by Skydrive. The nice solid body has been replaced (in the

Mark 2 and Mark 3 versions) by a casting around a bit of

bent copper pipe. Not as asthetically pleasing but i am

sure a lot cheaper to make.

Even the Lockwood catalogue shows this mark 1 version.

I am sure if you buy from any of these suppliers you will

get the mark 3 version.

The difference between the mark 2 and mark 3 ? They

deleted the temperature gauge !

I have one, or rather a pair. It does not work if the

water temperature is allowed to get too low, and

unfortunately the time you need the carb heaters working

(cold) is when the water temperature is low. Baffles required.

I am building a searey.  Unfortunately the builders technical sight is closed, but one of the builders had the piston installed, but the engine seized in about 20 hours. This would be third hand information, so take it for what its worth.
