Possibly lose vacuum very quickly with the single plane intake ..?
The bog can be produced because it is very rich in the secondary ones?
As I mentioned, with the 56 jets in the primaries the engine was slow ... in fact, a flat spot was produced between 1500 and 2000 rpm in WOT.
Although with the 55 jets it is produced, it is much less and improves a lot.
