Sudden new problem??

She's been running fine for 4 years, but was warming her up recently and still ran fine above idle, but foot off accelerator popping and backfiring??
Any ideas. Berryman's Chemtool into throat?

Maybe a coil or condenser?

Time to go down some basic troubleshooting processes. Try to isolate the issue to fuel or ignition, then go from there. Spark to every cylinder? Timing, dwell set right? What do the plugs look like? Gas good? Filter good?
