There is a kit you can buy to redue the carb .the gasket that acts as a fuel pump wears out.just as in some lawn mowers
More investigation and information required, possibly damaged piston rings or crank bearings.

Hi,
Try reversing the 2 fuel lines going to the back of the primer bulb,it sounds like they may have got installed wrong.
Thanks

The longest, and sometimes smaller in diameter of the two fuel lines, goes from
the carburetor to the bottom of the tank. Leave enough slack in this
line so that the filter that attaches to the end will rest comfortably at the bottom of the tank.
The
other
fuel line goes from the primer bulb to just inside the tank,
(about an inch). make sure that you get the right size fuel lines. The
plastic coupling goes on the end of this line, inside the tank. This
keeps the line from pulling out of the tank.
(HINT): When feeding the lines through the tank holes, cut the lines at an
angle. They will feed much easier into the holes. You can than cut them
off square, once you know that you have enough to work with.
If you need further assistance, just let me know.

Most likely ethanol damaged fuel lines. Sounds like it is starving for fuel. Look inside tank at fuel lines....if they are "melted" they need replacement. Its also possible that your gaskets inside carb have met the same fate too.
