A Tee Dee .051 piston will have a ring around the bottom. It can be seen through the exhaust opening if you bring the piston up near top dead center.

Both the above points are correct. Just keep in mind apart from the color of the carb body and the ring around the piston skirt they are identical.

I say this as it's easy to swap parts around. Look for both the ring and the carb body color. From a glance though the carb body color is a dead give away.

The one in the picture you posted appears to be an .051, to be sure though you would have to remove the muffler and look for the "ring around the skirt"

Another thing, if it has the TD P/C set, I would take the muffler off anyway if it has SPI the muffler will choke it out. It will run but will have little power. (Bandit)

It looked like it had a ring around the bottom of the piston but it had a 4 stamped on the exhaust port

If its a 4 that's the .049 the .051 piston would not fit in a #4 the #5 is the TD cylinder set with a slightly larger bore. Here's a pic of my 051 showing the ring on the piston skirt. Hope this helps (Bandit)
