I recently installed an edelbrock 1406 with an adapter plate onto my stock 350 motor. The qjet in the past needed rebuilding and I found a place that sells carburetors with a lifetime warranty, which is what drew me into getting the 1406. The previous carburetor was also stuck in a high idle. I did the replacement today and everything went smoothly. When I went to start the car, it started right up with a high idle which is what I expected to happen being that I haven't adjusted it yet. 20 minutes roll by and it is still stuck at this high idle, I adjusted the idle mixture screws and even the screw that controls the carburetors idle speed when it is warm on the 1406 and it did absolutely nothing. Some wires that I had near my headers even burned off, it is just a nasty situation. Does anyone have any idea what could be the cause of this, because I am truly lost on this one.... I did a full tuneup minus the pcv valve and this is still happening... I also blocked off the EGR valve with an egr valve block off plate being that the edelbrock 1406 cannot fit with an EGR valve. Can someone please help?
