The donk was playing up & after stuffing around, I bought a new Briggs 850 for the mulchy
New engine & blade boss arrived ( one of the lugs snapped off the old boss )

The holes weren't threaded so had to cut new threads - didn't have the correct tap, so it has 9/16 bolts

Fitted and ready for work

At the office......something l didn't realise was the shaft is longer so have lost about an inch of cutting height; not an issue as l only use 2 notches but a bit annoying all the same
