I was going to remove the impeller from this Giant Vac leaf blower. The engine though a rod and instead of tossing it in the "metal pile" at the dump I was going to replace the engine with a used on I had laying around (from a busted post hole digging earth auger). I searched the board and didn't come up with anything specific to this make. It does have a key that I can see. I'm still searching through the manufacturer's web site for instructions. I have it soaking in some BP blaster.
Anyone ever taken one of these impellers off briggs engine shaft (1").
