Too Rich

<< < (2/2)

rcwilbur:
Thanks.  I think that may be the problem.  Somewhere on the internet I found the specs for this carb and it seems that the jets and rods are the originals.  The car runs extremely rich, especially on the drivers side cylinders.  It runs so rich that it spits black soot on the drivers side. 

I guess I'll start with replacement rods, but I understand that these rods are no longer produced.

77cruiser:
Cliff probably has them, if not here's a set of 49's.

Cliff Ruggles:
We don't use or recommend the "K" series metering rods for those large MAB units.  They don't provide enough control of the part throttle A/F ratio.

I would get a set of our .044" metering rods for it, and put one of our kits in it while it's apart, set the float correctly, replace the PP spring and it will be fine......Cliff
