i'm trying to figure out if its normal for my truck to have a consistent 3 to 4 second period for the starter to get the engine to run. cold or hot, choke, half choke, no choke, is this normal? it always starts, i'm just wondering about the life of the starter. just replaced cap and rotor and @18 ft of vacuum lines with no change in starting. any feedback would be greatly appreciated. 85' 60, bone stock.
