Low Mileage
Long story short, I bought this car back having built it up 15 years ago. At the time I didnt have the funds for an AFR or rolling road tuning after I put the DCNF's on so I took a punt and left it at that.
After the rust work and a scratch rewire it has an AFR and I would like to get the jetting bang on.
So this is the state of play;
2x 40 dcnf 12
At the correct angle for an X
Tipo 1600
Deshrouded valves, everything lightened/balanced etc
Fast road cam, 421 headers
Venturi = 33 (roughly, someone machined these out)
Idle jets = 45
Mains = 125
Emulsion tubes = F30
Air correction = 200
Carbs are balanced.
At idle I have set the screws to give about 13:1.
The idle circuit is basically running at 12:1.
Running at higher revs is a bit leaner, it moves around a bit but is sitting at 13-14.
Any acceleration at all gives a little bit of hesitation and when it picks up it leans it out to 15.5 or 16.
I imagine smaller airs would be the first port of call, but basically looking for any obvious steers to get that acceleration figure back into range.
It pulls pretty hard as it is up to about 8500rpm.
TIA
