51 F1 idle and acceleration issues

I have a 51 F1 flathead V8 and I'm having issues with the engine bogging down with acceleration. I had the carb overhauled within the last six months and the truck was running smoothly. It is an around town driver and doesn't get too much action on the road. About three weeks ago I took it out on the highway and had her up to 50 mph or so. She backfired a few times but other than that ran great. There is always some hesitation when stepping on the foot feet. I have played around with the acceleration pump. Having it in the summer, regular and winter holes. That doesn't seem to be the issue. The fuel is fine as I added some Stabil when I filled the tank last winter. The motor runs fine cold but when it gets up to temp is when the issue of bogging down comes about.Thanks for reading. Any and all information will be helpful.

Verify the accel pump is actually providing a solid squirt from both nozzles. Check float level too.

Look for vacuum leaks. Also check timing and condition of the points.

I second this. Don't forget the condensor.
