Gunrush, thanks for posting the picture of the throttle valve. It looks like they have gone to considerable trouble to lean out the idle by having all those bypass holes in the throttle valve. The result would be an extra shot of fuel as the throttle moves from the idle position to the transition holes.
There may be a larger idle/low speed jet in the carb to go with that throttle plate.

It's my understanding that the EL46 came with this style throttle plate from the factory.

Based on the parts ipl... No. Sure would be nice if a dealer could do a quick write up with pictures.

The EL48 is 140.00

Well, for $140, that should be a difference worth exploring. Perhaps somebody can go through the EL48 and see where it differs from the EL46. Crikey, if it is only something simple like modding a throttle plate, somebody could make some bucks by modding the earlier carbs.
Obviously check the throttle plate, then
the idle/low speed jet
the size of the transition/air bleed holes
the metering spring
the size of the metering orifice under the metering valve.
One other potential issue could be how far the main discharge nozzle extends into the venturi.
Once we know what the differences are, then a fix could be designed.

There's defiantly tricks to make these carbs work but if a guy still has warranty it would be logical to get them swapped out. I know mweba, and I think hamish spent a lot of time trouble shooting these carbs and finding out ways to make them work. I've spent a fare amount of time my self using there tricks and a few of my own to get my el44 to run dang near perfect, still has s mind of its own when it's hot out though. Mweba has a few great Utube vids going into detail on his findings. There worth watching.

Sorry for not giving credit where credit was due, have you had a chance to get your hands on an El48? I think the over all tune-ecu software is different to right?

Bozo.
I'm still using the EL44 to fix the trouble prone ones.
Just FYI, I've recently seen EL48 carbs on the feebay for much cheaper. Not sure how or why someone has a lot of those to sell, but they're there. And about $80.
