    Hello Nong,

    You either have WEBER 40 IDF or Dellorto DRLA 40… Please clarify?

    We need the complete specification of the jets currently in your carburettors, and the choke size please.

    Both IDF or DRLA require low pressure fuel supply, 2-3psi maximum..

    If you are getting fuel coming out and smell, it might be that your fuel pump is supplying too much pressure.

    Thanks,

    Emmanuel
