WOTIAN Recoil Starter Pull Start Assembly for Briggs & Stratton 163cc 208cc for Generator Lawn Mowers Black 6 Holes with 130cm Rope (160mm)

Will this work for a Dek chipper model CH1?

Can it be used on my B&S lawn mower?

Will this fit Champion 2500, model 201153, 79cc?

The photos show a fully assembled unit with 3 mounting bolts and a pull rope. Does that pull rope need to be installed in the unit or is it a spare?
