Where can one purchase one of those fancy electric carb heaters?  I've been searching online and can only find plans from a fella on ebay...



I had a good episode in carb ice today on my 447.  Climbing out at 45 mph at full throttle the RPMs suddenly were dropping out and when I leveled it out and throttled back I could feel the itermittent misses...  In talking to a mechanic very familliar with Rotax and a few other sources, it most defidently was carb ice...



Anyone have a source for the electric carb heaters?



Thanks all,

Fly safe,

go to this web site  http://www.leadingedge-airfoils.com/   

  

             Products     Manufacturer     Model     SKU     Price          Engine        Carburetors, Electric Dual Bing Carb Heater       Bing               J9114               $259.95                                                           It is a bit pricey....I do not know anything about              them...have never used it, but am interested in any info from people              who have., or anything else pertaining to carb. ice in 2 cycle rotax              engine .   People I have talked with about carb ice              in the 2 cycle go from people who have had no problem to people who              believe they have...nearly all have had forced landings, some think              it was caused by carb ice others dont think so. I am in the process              of studying the issue and will report and info If I  feel it              usefull.

Looks like the price came down...



 They used to be over 300 bucks

That ones for a liquid cooled engine... maybe a 912...  I don't have any water in my 447...



I know they exist...  I just can't find one.  Maybe I will have to buy the plans and build one myself from the guy off ebay...



Check it out and see what you think.

Long time ago there was an elect carb htr made/sold by a guy in  

Alaska. don't remember what eng/carb it was for. Archive?

All this talk of carb icing... I had carb heat in my T-Craft, of course, 

but not in the  503 powered borrowed Quicksilver I was flying until 

recently, nor the PPG's (and it never seemed to be a problem)... what about 

the Cuyuna (I'm buying a Cuyuna powered Ultrastar)?



Of course an electric carb heater isn't an option on a plane with no 

electric...

Hi John,

            Back when I had to "put Down" because Carb Ice had my engine running slow & ruff , I started looking into a Carb Heat...



  I thought it was Aircraft Spruce who stocked them....for around $350 

( Dual Carbs )  



   I "DID" talk to somebody that had them on their carbs , they said that it robbed a little power , but he hadn't had the problem again....



  it's more or less an electric "vest" for your carbs....



  I guess the power loss is from warm air....?



  I'm gonna see if I can hunt down the ones I'm talking about.....

 and they were made for ROTAX

Sure, you will have some power loss when you use carb heat; in fact that's 

how you check that it's working (rpm drop) during your runup.  But you 

don't use it all the time, just for partial throttle operations (i.e. 

descent and landing) since that's when you're susceptible to carb icing... 

it's rarely a problem at cruise power or above.

When I got "My" Carb Ice....it was on Take-off

 The Carb Heat that I was trying to look up can't be found.... I do remember that it was on "all" the time....

 I saw the one listed in L.E.A.F.  , I like the stuff that goes with it....A switch and indicator light... That way you wouldn't have to have it on all the time....

 When I got carb ice ,  I circled back to the runway.....hoping that the engine would "Clear" , but it didn't , I circled a couple of times , but I was coming down....not enough power.... I haven't gotten carb ice since...

( that was my Powered Parachute / 582 )



  But I think the carb heat would have had time to work....

 I don't think it would be that hard to make a carb heat box , using a little plumbing from the exaust tubing....



 I think I saw the temp needed is around 90 degrees , that shouldn't be hard to do... 

  Gotta Fly...

What I've heard (and this is really a question, not a contribution) is

that heating the carb body (via water or electric) is better than the

"GA method" because the GA method routes hot air into the carb, which

lessens the power... but that heating the carb body prevents ice from

forming but which results in minimal air heating, thus trivial loss of

power compared to the GA method.



Does this sound right?

Robert, both approaches will reduce the volume of the air charge 

reaching

the cylinders but the water heater is superior.  Naturally depends on 

whether

you have hot water available.



This is my homemade water heater strapped to my homemade intake 

manifold.

It was an after the fact fix to both help vaporization and prevent carb 

ice.

Works well.

What are you running for a carb? Looks like an old one barrel Holley.

Why is the water heater superior?  If the water is, say, at 180

degrees, and an electrical system generates, say, 90-degrees, (or 180

if you twist the rheostat!), then why would the water heater system be

superior?  (This isn't rhetorical... I really want to know!

RHEALLY now!



Maybe my isolated opinion, but in my case the heat gets added to the

incoming air after the venturi which maintains the volumetric capacity

of the (rather small) carb.

The heat from both the aluminum intake manifold and the saddled

muff transmits through the metal to the carb base, which is where

the chunks of frost generally tend to accumulate.



I remember frost forming at the carb base of an airplane engine

running on a test stand in Los Angeles at an OAT of 70F



It can happen to YOU!
