anything is fixable with enough effort, but I'd just save this for parts

a new motor needs to run-in for quite a while to develop full power
 
OK a little more help. i had to take the end of my muffler off to get the second motor to start. when i did some metal pellets fell out I'm guessing its a piston ring that got eaten by the motor hence the loss of power. I'm scared to open the top of the motor cause i read it needs a tork wrench.
 
A lot of mufflers have those pellets loose in them - I've always assumed them to be parts of the catalytic converter that didn't get bonded properly. I often hear them rattling around in mufflers new, right out of the box.
 
they were both used. doesn't sound exactly as good as the previous motor. kinda knocks or something at higher rpms.

first, take out the spark plug & turn the motor by hand to see if you feel the piston bump the head

next use a screw driver to pry up a bit on each side of the crank to see if one of the main bearings is loose

if all that is good, it may just be a noisy motor
 
that part would fix it but it's a "heck" of a job (why is the "H" word blocked?!?! are we in kindergarden?) anyway... try using the old carburetor (thing that the fuel goes into) as the new one might not be adjusted properly and if it doesn't get enough fuel, which sounds like might be the case, it can ruin the engine. first try swapping the carburetor it should fix whatever problem you have. what type of carb do you have? pics would help.
