yes
your old one has 2 jets that are visible from the top of the carb doesnt it?, later carbs have the main jet buried in the body, its more like a grubb screw. However a tap can be got in through the 12mm access pug on the float bowl. The body can now be tapped to take the replacement jets. yours should just be a strait swap.
Ive no direct experience of your carb or those actual jets but what have you to loose a crap pint of lager/beer costs more?
