I hear you on the back wheels being the most used, that’s how I do it too.
The machine with the worst front was originally bought by a friend’s father who is a bit shorter than me and would have used it more flat, not having the leverage. I should have done something about them before but, it’s only now at that I’m looking at this more from the point of view of the machine being as right as I can make it. They’ll be fine if I can find some solid replacements.
One blade carrier is ok as far as I can tell, I’ll pull it off and clean it back to make sure there are no cracks lurking. I’ll get my act together and take some photos. I haven’t checked the other one yet.
Do you happen to know how the air filters originally worked? There’s a pair of the older blue Victa ones fitted but it looks a bit heath robinson. Were there originally caps held in place by a flange plate?
I only seem to have the flange plate now and I can’t remember how it used to work.
