inlet rubbers

[Stretch85]

Hi all, I have an air leak round my in let rubbers, revs hang at about 4 thou before dropping right down, I sprayed carb cleaner round them and it revs up so definate leak. I have replaced the o rings under the inlets, there are no visable splits and all carb clamps are tight but I still have the leak, any suggestions?

Take the rubbers back off and try putting liquid gasket in around the O-rings . Belt & braces
