Weber 38/38 jet size..?

[hydroli]

I finally started the engine,

After having problems with the oil, which been trown from the engine by an incoherent fitting, I've been able to take a ride!

It doesn't worked like I expected. The plugs are black as charcoal. After discarding a hypothetical barometric pressure drop, I figured that it could be caused by too big jets!

What should I start with in my tuning while using a Weber 38/38 ? I have a mild lazer cam, nothing big, and a HO manifold.

Thanks in advance for your clues.

what are you running now,don't use the number on the jet ,measure it in .000

[hydroli]

Main jet is .056, air corrector is .067

[hydroli]

Both port are the same, they are synchronised. No one is primary and secondary.

What should a #145 jet measure???

[rad15E]

a 145 jet is 1.45mm which measures to .057 -i have 2 38-38 webers and they vary between .057 and .061 put the same size in both sides since this is a tru 2 barrell carb
