Repair Difficulty:

Medium

Time Spent Repairing:

30-60 minutes

Tools Used:

Screwdriver, Pliers, Wrench Set, Nutdriver

Carburetor gaskets disintegrated causing flooding and leakage.

Use the ereplacements parts diagram. Make sure the two fuel line to tank hoses are properly installed as this unit was a junk unit and the two hoses were swapped. Now the unit runs like new starting on the second pull each time. I love this powerful blower but my neighbors hate the impeller noise so I can only run it when they are at school, shopping or work. I took a picture of the hose layout plus the rest of the unit as it helps down the road if further repairs are needed.
