[Avodah] Eat Karpas - Leaning?

[SBA]

From: SBA [mailto:sba at sba2.com] 
Our Minhag has always been not to 'lean to the left' when eating Karpas.
But learning KSA (119:3)this morning, I see that it rules that one should do
so.
The MB doesn't mention it and I have yet to find any tana demesaye.

I had actually checked out the sefer Likutei Maharich (which is usually one
of the first seforim I consult when after information on minhagim or
nus'chaos etc),but surprisingly couldn't find anything there. 

An einikel of its Mechaber (we have a whole bunch of them here) pointed out
to me that I was looking in the wrong section,ie,"Hanhogas HaSeder". 

He directed me to the following section - "Seder HaSimonim" where indeed the
LM  does discuss this. 

He writes that the Abarbenel (and KSA) require 'heseibeh'for Karpas, while a
number of others do not and concludes that the minhag is not to lean.
