Bvs143 carb replacement

[mowerboy87]

Hi I have a BVS143 engine with a 23020104 carb on it. I cannot find any for sale in the UK (fir a sensibleprice). I found some non informative direct replacements in America but no part numbers.
Does anyone now what carb I can replace this with if there's a newer part number or something?
Thankyou

Please post the Tecumseh spec number, E-xxxxx. I’m coming up with a different carb number.
