Hey, just got an old deere that’s been sitting for 8 years. It’s in pretty good shape. I clean the gas tank, new filters and gas lines, then cleaned the old walbro wr7-5 carb. It starts up with sprayed gas into the carb but only has half power and dies out, won’t restart without spray......can’t find a rebuild kit for this old walbro. What other options?? Try cleaning again? Fuel line primer bulb? Tilloston?
