I have a 1960 w500 with a 318. It wasn't running when I got it, but now it is. Has good compression. It runs good till it warms up. Then it loses power and backfires. I adjusted the valves warm to .010 int. and .o18 ex. I wonder if they should be readjusted to a larger clearance. It doesn't seem to have any rocker noise. Does anybody have any ideas?
