   Two approaches.  Either pull the motor and take it to a motor shop, or find a new replacement motor, and start fresh.  It could be the capacitor (relatively inexpensive), the centrifugal switch (more expensive), or windings (fuggedaboutit, buy a new motor).

   BEFORE GOING THE EXPENSE OF A NEW OR REBUILT MOTOR. ALSO TRY CHECKING THE BREAKER i HAVE BEEN TOLD THEY CAN START GIVING OUT SOMEWHERE AFTER 5 YRS. MAY NOT BE THE PROBLEM BUT IS WORH A TRY

   Silly questions, but like to start with the obvious.

   - Have you started plugging it into another circuit?

   - Using an extension cord?

   - Plugging into a different outlet?

   - Is anything else running on that circuit when the saw is?

   A loose motor connection, bad plug or outlet could cause it to draw more power.

   Just being real dirty inside could cause problems. My compressor motor was blowing the breaker. Took it to a motor shop. He pulled it apart and cleaned the contacts inside. Blew the crap out. Now it works perfectly. All the built up crud in there was forcing the motor to draw too much power trying to trigger the 'start switch' (I think that's the right name. Nothing wrong with the motor at all. Cleaning and lubing will do wonders sometimes.

   I'd start by pulling it apart and blowing out the motor, or having someone else do it.

   If that isn't it then start taking covers off and checking electrical connections: Motor connections, motor plug, outlet. Swap breakers, or plug into another 20 amp circuit. Also look for any signs of arcing or carbon deposits, blackened faces on plugs, crimp type electrical connectors that are barely connected, a damaged section in the cord, tightly pinched wires, ect.. Often it's something real simple that causes this.

   Good luck

   Does this motor contain carbon brushes? They may be worn out. Very cheap/easy fix.

   Sharpen the blade.

   As soon as it blows again, feel the blade, the motor, the cords, and swtches, plugs, etc to see what is warm.

   Or use an induction ammeter before it blows to see what it's actually drawing.  Pretty much guessing otherwise.PAHS Designer/Builder- Bury it!

   Probably the correct answer... A good heart embiggins even the smallest person.
