It's not a matter of the ignition handling it. There are plenty of guys out there with Weber and Dellorto 48's, even "51"'s with the stock electronic ignition. It's whether or not your exhaust and your housings have been worked to handle a bigger carb.

Good luck! I was thinking the same thing. I have Eldebrock exp. It's all I ran on my V8's but EVEYTHING I've found suggestes that a carb setup for a rotor is Extremly speacilized and that when and if you get it right You'll have sopent more than Buying one that's ready.Chek out Mazspeed.com they have been a great help so far and really Know about these carbs.
By the way I'd always take a free Eldebrock 750 I'd find something to put it on or trade it for that I could use!

edelbrock carbs are junk, thats why nobody is responding, ... its a carter style carb thats usally used on replacement stock applications .... give that carb to your grandfather, he will be able to use it, and it will work well too!!!
for your mazda you need a weber carb to get the performance that you need and you can jet it up later when you do more mods easily too..... now what do you want to do?/

A little impatient tonight eh? Ha ha ha.
Assuming that the 750 stands for CFM, that's way too much carb for a stock port 12A. Just off the top of my head, I think all a Stock Port 12A wants is 425 CFM or at least in that range. Basically you *could* get it to run, but never well, and never throughout the rev-range.
Again, I'm assuming that an Endlebrock of this size would present the same difficulties as a Holley of similar size, so don't jump down my throat.
EDIT: Also, I'll take that donkey.
PS. Only if it comes in yellow, I want a fast donkey.

Anything over 450 CFM and you'll have **** for low to mid range.
I can modify your existing carburetor for you. I'll put it up against a Weber. Id be curious to see.
& Robert, stick it in yer *** before you even say it!
...friggin Weber pimp!
pbrx7 & LVRX7-
Webers are fantastic carbs that have everything changeable so they can be easily tailored to run on a rotary. They are tuneable - meaning you can change the power curve.
My SterlingCarb is a stock Nikki modded to flow more volume (from 313 cfm stock to 430 cfm) with replaceable air jets to allow for far greater tunability.
The Racing Beat Holley carbs are also specially tailored like the Webers to work on a rotary. But they offer little tunability.
Unless you know an awful lot about carbs, you can't expect to take a carb from a piston engine and make it work very well on your rotary.
And anything over 450 cfm for a NA stockport 12a is overkill.
Mathmatically, the NA 12a only needs 344 cfm @ 8.5K rpm @ 100% VE.

45 DCOEs second hand over here go for about $50-60. I will happily score one for anyone who is interested. Don't know if I can get better deals that you can on the parts. PM me if interested.

Airflow is my life
You'll spend way to much time and $ trying to get it right. If you wanna try, go for it. Nice thing about edelbrocks is the metering rods. easier to tune. But you got along way to go to get it right. I'd take it, sell it, and get something proven and easier to work with. But if you wanna go your own way, have fun and ask questions.
