258 with a rebuilt mc2100 1.08 venturi. HEI/TFI hybrid, new filters, new tank, new lines. Stocker fuel pump. Manual choke. 79 CJ7.
After reading not sure of jetting on carb. It came off of a late 70's Ford F100 with a 289 or 302.
I am carb ignorant, so maybe this is all in the settings and tuning.
Been a long time since she ran, so I gave her plenty of fresh gas and fired her up after replacing the tank.
My tach is not connected, I have the mix screws at 2 turns, idle is by ear at the moment.
She will fire right up, if I lightly keep my foot on the gas she will idle, after a couple minutes she will idle on her own.
It smells rich. Looks like it's running rich too based on the exhuast.
Do I need a FPR for this carb? I've seen threads of them for the Weber.
Where it was leaking out on the return line by the firewall were it goes from rubber line to metal, could it be over pressurizing and sneaking out that line?
I saw a thin trail of gas on the graveL as I put it in the garage, couldn't see anything wet other than the return line where I mentioned above.
Are the jets physically numbered? Can I pull one and it will have #47 or #49 scribed on it? How much could timing affect my situation?
I need to check the timing, tweak the idle, and in general try to tune the carb and get it dailed in.
Was really curious if she is running rich and needs a FPR or could it be needing smaller jets?
She has no road time, trying to get her safe and relaible enough to do a drive through the town and feel out all other issues.
Thanks for any input.
