What is the recommended and/or best fuel pressure for a Spitfire MK III =
with a single ZS carb? In checking it shows 4.5 -5 PSI on a gage. I try =
to keep it close to 2 PSI or less on my dual ZS equipped TR6 or it =
develops a cough at idle, so it makes me wonder if the fuel pump is =
overwhelming the float needles.
With the Spit (this is the road Spit not the race car) it idles fine but =
the first attempt to accelerate it bogs down then catches then bogs some =
more and so on. I=92m going to switch the distributor out and the coil =
to see if my fuel problem is actually an ignition problem=85you know =
that old saying.
Thanks
