<x-tad-smaller> After my 68 imperial has warmed up from running about 15 minutes it occasionally will not start for about 20 minutes. I have done a lot of work to try to fix this. I removed the intake manifold, replaced the valley pan and painted the manifold. I installed a spacer between the carb and adjusted the floats in the carb. I checked the heat riser, it is broken and laying in what i assume is the open position, all the way back and it does not move when i rev the engine. Also the heat running through the manifold exhaust port makes the manifold so hot it discolored my engine paint job! I checked and the exhaust ports in the heads and manifold are free and clear of obstruction . I do not know what to do now! please help </x-tad-smaller>
