Hard starts after running
Along with all the above, if you don’t already have one I’d install a wood/fiber type insulator. Running a 625 AVS2 on a 318/360 Performer atop a 90 318 in a W150 and had heat soak hard starting at stops as well, the Edelbrock insulator (can’t remember part#) helped quite a bit. Still have to slowly depress the pedal as I start cranking but it fires up and clears out much quicker using less pedal with the insulator.
