Hi Bruce
While waiting to obtain funds to complete the Mark 3 lawnmower I have started to work on my Victa VC 160 Mark 4 lawnmower. The mower runs fine (starts first pull) but when set to grass cutting speeds very fast and sounds like it is going to blow up. There is a wheel that you can turn on the carby that says idle adjustment, do I use this to change the revs when the mower is running?
