twin su's

[minigreen94]

hi,
we have flooding float chamber on the right hand side as you face the car.
the needle is of the fixed type so we cant really adjust it. we have cleaned the needle and underneath it several times and it runs fine for a few minutes before flooding. is it possible to have too much pressure with a standard mechanical fuel pump on twin su 1 1/4???
any help much appreciated, thanks

Both carbs see the same pressure, soo unlikey.

Problem is the needle valve (not the carb needle!) and/or seat wear. Go for viton-top replacement. Adviceable to replace the valves in both carbs at the same time.

Needle valve located in the lid of the fuel bowl, recomend a couple of these kits as a starter.

thanks for help, we're going to rebuild the carbs with a kit from minispares.
thanks again.
