Im struggling with this darn carb. Its an Edelbrock 1406 with a performer eps manifold and a mild cam. I rejetted it what the local engine builder says is optimal for this altitude (5200 ft) and it ran GREAT in the summer. Now that theres a foot of snow on the ground, it hates life miserably. I have to pump the pedal about a hundred times and crank for a good 30 seconds to get the thing to start. My choke is not coming on (easy fix, just havent had time to do it yet) so I have to feather the throttle for a good 2-3 minutes to keep it running. On start up it idles at about 400 rpm, but once it is up to operating temp, it idles at around 900-too high! The truck refuses to run right until my water temp reaches about 165 degrees, I have a 190 thermostat. You have to nearly idle while driving until it reaches temp, otherwise it chokes itself out and dies. Once I reach temperature, it runs great! BUT it studders when applying throttle at any cruising speed. I think I'm running a little fat. I was wondering what jets and metering rods you all recommend? I cannot recall what I put in it.
