so allen and i were playing with a cobra last night, trying to get it up with some shots in the dark.

got a poor idle with the idle screw all the way in and idle air circuit pretty lean.

75 jet, harder to get the idle to hold with a 68. kicks over, not much power.

dollorto 21 race. 75 main, 45 idle, 7 needle, stock diffuser(not sure needle setting)

metra65 puch 1speed previously ported for a polini (matches well i hear) proma gp.

its a similar set up to mine but i have a non ported 2 speed, so we started in that jet range. cant seem to get a good go out of it

which way should we jump looking for it to hold
