You haven't stated the model you're referring to.. Here's a link to a Black and Decker blower vac manual, but it might not be your model as I'm having to guess due to lack of info.
Check and clean filter. If electric check brushes for proper motor operation. If battery is used, make sure it is charging properly. A bad battery will not work unit properly.
Try pulling the air filter off and see if it picks up. Also a minor carb adjustment may help. Also make sure your fuel isnt old or watered up. See if you can find alcohol free gas in your area. It may cost a bit more but it saves on repairs!
There are two openly accessible screws on the back for carburetor adjustment. The one on the right is for low speed, the left for high. You may need to turn the low counter clockwise a bit. Below those two screws is your idle adjustment, and I suspect that is your problem. Turn it clockwise and try it again. Also, check that your fuel/oil mix is not too rich.
Check to see if the muffler is blocked.There is a screen (spark arrester) at muffler exhaust these get blocked. Usually 1 screw holding it in. Remove screen and replace or clean. I use bernzomatic torch to burn out these deposits.
Is the new spark plug wet? If not, the machine is not getting fuel (fuel filter, carb, etc.) If the plug is wet, you may not be getting spark (bad ignition module, short in switch/harness, bad plug (yes it does happen with even new plugs)), or flooding due to incorrect starting procedure or clogged airfilter. Stale fuel can also cause an engine not to start as it lacks volatility. If in doubt, take it to your local dealer.
