alrighty
i have a 79 chebby 3/4 ton 4wd truck 355 sbc, runs perdy good. but my one stumbling block at the moment is at about 1/4 throttle the truck stumbes and picks back up then is fine through the rest of the powerband.
my question is it fuel or spark?
i have a GM dist with recurved weights, and springs. the cap rotor look in good to great shape, plugs are new wires are in great shape.
as for timing i cant remmber what its set at. to be honest i kinda fine tune it by ear. i had a light on it once then just move it left and right till the idle smooths out and then take it for a spin and see what happens. (prolly not the best way but its how i was taught)
as for fuel it has a 600 cfm carter AFB on it with edelbrock metering rods set at one step lean. i looked online and cant find the part numbers for the kit i used. ( i willl look later)
but for now the generic question is would this be fuel or spark?
man i hope i make sense.
thanks
