A year or so ago I posted a question about 2 dead spots in my RPMs while accelerating.Last Friday I took the plunge and cracked open the carburettor and found the venturies (the round things in the carb throats) worked loose and were not supplying the right amount of gas,effectively leaning out the mix.Tightening the 2 screws each did the trick.There must have been some pulse-resonant thing happening at those 2 RPMs to make a Brick-Wall effect,but now,my little truck RUNS!!!

Even though I’ve moved on from the Mazda pickup, I still like to hear about what fixes them. The rare fixes are the best ones.
