Hi all, new to the forum, ive tryed searching for this but no luck.
Ive just got a 92 with a 1.6 transplant from an astra gsi (thats as much as I know, but believe its the same as in novas anyway, e16se). Its fitted with twin weber 40s, but it has a real flat spot in fueling, running far too rich I feel, so ive pulled them and going to tune, but the trumpets fitted are really short, maybe 15mm, could this be causing a lack of airflow over a certain range?
Would longer trumpets improve performance and if so what length have people found works well?
Cheers,
Aidan
