There's no /b/ in these words; the bh there is just a means of representing a diphthong (/ai/ or /au/ depending on dialect).

...ach taitníonn muintir an tí seo go maith liom féin bíodh is nach nach bhfuil aon cheo bog ag baint leo, fearacht an chuid is mó de na Polannaigh.

Diabhal ciall is féidir liom a bhaint as an bpíosa so i gcló trom.

bíodh is nach = although not ("be it (even so) that not ...")

(double nach is a typo, I'd guess)

ceo = nothing,
aon cheo bog = nothing at all

bain le = touch, concern, interfere, relate to,

Depending on context: ... though nothing at all interferes, relates, concerns them, is connected with them

Found out that the word "pincher" was also applied, sometimes, to a general (heavy) labourer.

Sliocht mearaithe eile. Tá mo dhuine gofa isteach i dtigh tábhairne i mbolg an lae.

"Casadh John Delia ansin orainn agus go leor eile as Conamara, agus mura raibh 'game' ann ní lá go maidin é."

I'm not familiar with "game" but I'm guessing it means the same as "craic".

That was my assumption, too, but I don't understand the connexion between this and the rest of the sentence. Is ní lá go maidin é an idiom of some sort?

Cor cainte atá ann - nár tháinig mise trasna go dtí seo. Cuid mhór samplaí de le fáil ach 'ní lá go maidin é' a ghúgláil.

Níl 'ní lá go maidin é' ag FGB ná ag De Bhaldraithe, áfach: FGB - ''ni lá go fóill é'; De Bhaldraithe - 'ní lá fós é'

I've heard that often, maybe it's a Conamarism. But I couldn't explain where exactly it comes from.

Go raibh maith agaibh, a chairde. Ní fhaca an cor cainte sin riamh, go bhfios dom. An chéad údar as Conamara a léas, 'sé Mac Amhlaigh é.
