Another update. I put a lot of bottle brush branches through it and it started not feeding right and generally feeling something was wrong.
The carby bolts were starting to vibrate loose so tightened them off, but worked out the deflector plate I made under the deck had broken its welds and was about to come off.
After rewelding it (I can now half decently arc weld) I got an old Rover blade, cut 20mm off the winged end and welded in as a brace to the back panel where the victa axle runs through. Cut a bit more of the catcher off so it would fit right.
And MF, I have taken to throwing the occasional lemon down the chute
I do regularly stall it now. But will run it until something happens to it. Funnily enough, I know for a fact that the motor is 12 years old today 21/7/22
