Hi Ironbark, I think you are overthinking things too much unless you are planning on a restoration back to something like original. If it is good wheels you are after (hard to get anything Victa these days) I just cut the back of the stub axle off and punch the stub out and fit 1/2 inch axles from another mower with good wheels and the you have a big choice of wheels because most use the 12mm or 1/2 inch axles. There is nothing in the 7/16th range that Victa use. Always plenty of Sanlis around and they have reasonable wheels with decent bearings. Not sure what axle clips you are talking about but a couple of days ago I was putting wheels on a little project sidethrow, bit earlier that yours and I just used the standard Victa axle clips and a couple I gave a bit of a hit with a hammer to tighten them up, nothing unusual about that. The plastic cap then prevents the clips from coming up. Not sure what you mean about the cutting height, are the blades too low compared to the skirt, if so just lift the motor up by screwing on another nut under where the motor bolts onto the base. There were so many variances in the way the motor fitted on different bases and if the motor was taken off an alloy base then it would need the spacers under the motor. As for the air filter I would just use a snorkel from a G4 type or a Rover, (think I threw a couple of Rover ones in the bin last week) and the just use a standard throttle control from any other mower. I find the Rover throttle is probably the easiest to fit. Plenty of ways to solve these problems and give the mower a new lease of life. I hope the 80 items you are chasing are not all for the little sidethrow. Here is a pic of the one I was playing with a few days ago, needs a set of rings and will be good for another 20 years The second one is a little 125 that I got from the side of the road and it is a cracker and I use it quite often, such a beautiful machine, so light and easy to throw around
