Aerocarbs any one used one of these

[animal]

HI I am needing a better carb set up for my Subaru.
A Pilot Friend of mine that has a baby ace asked me if I had thought about the Aerocarb,that they use on the Aerovee conversions.

They make this carb for engines up to 160 h.p.

I looked at the chart on the website and the have a model for engines of 90-125 h.p. , my EA-82 is supposed to be about 115 h.p. I do like the fact these carb's have in flight mixture control.

I think this alone makes it worth the price,how many here how spent hours trying to get the mixture right.

Now the price is $395.00 but on that same note, I have seen Harleys carbs that cost more and do not have mixture control.

Take look at the web site and let me know what ya think.

Looks like the "Posa" that I had on my subrua a long time ago. Ernie called it "a controled drip" carb.

BUd how did the Posa do for ya? these are pretty much the same design,but have inflight mixture control. I had a Posa on a hand proped V.W. and it was a B to start. I figure a fuel primer would be of alot of help, but of course My sub. does have electric start. so it may work fine, I think I would mount it in a down draft style. as I remember my Posa dripped gas before starting.

your input would be great,I am looking for honest input.

the website ,makes it sound like the perfect Carb for the subaru I am using.
looking at the 35MM version.

Tim,
I have a Aero 35mm on my Corvair engine, I think the 35 would be to much for the smaller Sub, maybe the 32mm would be better? I have not started the engine yet, might today, hope it starts:D:D

Mine is not a stock EA-82, mine has a Stratus grind cam and is rated at 115 h.p. and will be turning high r.p.m. with the redrive I have.


let me know how yours does, what h.p. is the corvair?

Looks like a great carb since it doesn't get icing. Would like to see how it performs. Harry

Harry yeah thats is another thing I like about it, Plus the inflight mixture and no floats to stick, now like the Posa carb you will for sure want a fuel cut off, maybe even rig up a mercury switch to cut off the fuel pump if the Gyro went inverted in a crash or roll over. also if ya have it feeding into a small header tank, the header tank gravity feeds the carb so in the event of a roll over, it would be above the tank and not way for more gas to flow upwards. to the carb. I think is has several advatanges, was just hopeing someone might have already been flying one.

I have a 32mm Aerocarb installed in an EA 81 direct drive. Like a Posa it continues to feed fuel until the mixture lever is closed even with the engine stopped which is the major drawback. Adjusting the mixture is straightforward and installation simple since it can be mounted at any angle. I didn't see any performance gains from my previous carb installations (Holly and dual Webers) and fuel consumption is similar. Icing has never been a problem unlike the Webers and Holly.

Starting requires more coordination and for my downdraft hand start installation goes something like this. With throttle mixture closed switch on fuel pump. Fully open fuel mixture for 5 seconds. This primes the engine. Pull through 2 blades with ignition and fuel mixture off to move the charge closer to the combustion chamber. Ignition on, mixture open then promptly start engine before it floods. It typically starts on one blade pull. If it doesn't start within about 5 blades remember to turn off mixture until you sort things out.

When shutting down allways close the mixture control to stop the fuel flow.

I've thought of installing a manifold vacuum operated fuel switch like some motorcycles use but haven't got around to it yet.

Another peculiarity is that at low throttle settings the manifold vacuum tends to suck the throttle slide against the housing resulting in high throttle breakout force. As the slide opens and manifold vacuum decreases the throttle force decreases significantly.

All considered I would recommend the Aerocarb just as long as you are aware of the "controlled drip" feature.

Dino Ok thanks thats what I wanted an honest report, I know about the controled drip the Posa carb was the same, thats why I wanted to mount it down draft style,I remember on the Posa, they said to turn the fuel on, count to about 5 and turn it back off, then start the engine and as soon as it started turn the fuel back on.

Do you have a pic of your set up?

[BUD ONEAL]

I never cared for the posa. To much of a hassle to start. did'nt have a air cleaner and worried about that. The fuel burn was not good.

animal,

Here's a pic of the installation.
