So the newish AVS/AVS2 carbs from Edelbrock come in a manual and electric choke. I have the manual version and wanted to order an electric choke kit, the same as I have done with AFB carbs in the past. Apparently there is no kit available. In fact, Edelbrock says that manual AVS carbs can't be upgraded with an electric choke. I have to think this is BS - the body of the carb even has the bosses for the choke, even though it's the manual version. Has anyone figured out what's different between the two? Thanks

That does seem odd....

My guess = Missing vacuum port hole for the choke pull off piston that is inside the choke body???

I have a 650 AVS2 with the electric choke, but I can't tell you what the difference is to the manual model. I just made sure I ordered the electric because a manual is a PITA. It is off the car in the basement so if you need a specific view let me know and I can pull it off the shelf.

Yep, the mounting bosses might be there but are they drilled for vacuum?

Do they have to be? The chokes on these are electric, not vacuum.

There are no vacuum operated chokes. OEM carbs typically have a vacuum pull off to keep the engine from being too rich after it starts. Aftermarket carbs don't typically have them and while the electric choke assemblies on these work they are less than ideal. Some carbs that were originally manual choke versions may have the bosses to mount an electric choke but may not be drilled and tapped. That of course can be rectified. Otherwise I'm not familiar with the Eddy carbs so I don't have a specific answer for you but if the bosses are there you should be able to do it. I've converted many Holley mechanical secondary carbs to vacuum secondary and vice versa. If the basics are on the casting you can modify the rest.

Does it take this electric choke?

Carb Side

Well there you go. If that boss is on the carb body you should be able to drill it and make it work.

Well look at that. That does look like it, wouldn't have guessed it was vacuum as well. Here are some pics for comparison. Model 1912 vs 1913

I think that's the AFB choke and not the AVS? (EDIT - looks like they have upgraded across the board) Apparently these all have a vacuum aspect to them, last time I modified one was twenty years ago though. The AFB must have had a port plug, I don't remember drilling anything.

Anyone know if these new AVS's use the same body tooling as the originals? I've found a few threads on adding the AFB style electric choke to an original AVS. Leave it to Edelbrock to make something simple into something difficult.

It looks like the lever is slightly different.

Pretty sure I had to change the lever on my AFB - they gave you one in the kit or a whole new shaft. The position of the electric choke arm and linkage look the same AVS to AFB too.

I think that the brass plug on the very top picture is the hole for the vacuum , they just plug it on a manual choke carb.

Note the first sentence.

The one that is in the base plate.

So what? Believe everything you read?
Looks to me like it can be done pretty easy. Need to change the choke blade lever, remove the vacuum plug or drill it, maybe tap the mounting boss holes as well but still very doable.

yeah in the front passenger side, below the mtg hole pattern.
