So I’ve got the timing set at 4 degree’s before TDC, point dwell is in between 31&32 degrees, the idle is set at 650rpm. The truck idles great but when I give it gas it will about 1/2 the time back fire through the carb and sometimes through the exhaust. The temp light will also light up about 10 min after starting it. Any ideas what to look for? I was told by someone here in town it could be a stuck valve which I’m assuming a compression check will help figure that out. There is no smoke coming out of the tail pipe.
