135 HP missing at 3,200 rpm

[circle hook]

what would make the engine very slighty miss at 3200 rpm, 3000 rpm is fine and 3400 rpm is fine but that one spots got me going, fuel pump rebuilt, new plugs, spark in all cylinders, good compression, DVA test is all in specs, whats left that i havent checked if she were out of timming it would run bad at more that just 3,000 rpm Thanks Bob
