Fuel flow and spark are good. My GUESS is it's a carb or carb adjustment issue or possibly some other fuel issue - i know the lines are good to the carb but not sure beyond that.
The case that covers the carb is missing a portion of the top of it and the other side that covers the muffler is cracked/broken where it attaches to the unit. Handles have rust on them.
Finally The bolt with the black knob on it broke when I was disassembling the unit. I unclosed the broken pieces and replaced the bolt with a regular machine screw, lock washer and nut in the handle.
