Any jet wizards have comment on this?
I rem on old comment made by a holley expert yrs ago...I spent a lot of timelisting to those who know stuff...numbers on holly jets dont always relate to diameter but rather flow, and things like things champhers and position change how the fliuds flow thru them.
but it actually runs like it's fuel injected except for this lean flat spot
yeah..that because most of your rpm range is in the effective range of the carb....
Which then gives the engine a very fun response in that rpm range....
Thats why with my engine, cam , carb, manifolds valley cover, all down low is so bloody economical plus in that rpm range 1200 to 5000 its so responsive....damp road, forget pulling out into a smallish gap in trafics, and take off normal at a interection, cars are why behind, if damp rear wheels break away.
I have been thru all my old boxes looking for jets but non for that carb...yes I understood what u meant in the 1st post.
Just had a thought thu, will check out a local speed /workshop guy he may have old stock/ bits.
