Hi fxxrrr,
That spring arrangement is not one I’ve seen before. But it works! Truth be known if they are needed then something is v wrong with
the drive. Might just be gummed up as Nath says. But it an ingenious solution to the problem!- at least in the short term.
I just had a rummage in the shed. I thought I might be able to help you out with your wheel problem but the ones I was thinking of will have the same problem- too wide and no room for the collar. Sorry

Cheers,
Cheers Guys
both for having a rummage for wheels and input on the springs,
I have rims its just tyres and tubes im short LOL
It may work fine without the springs, it had a bias when i got it because of different size springs creating it, Once i get it all tuned up i will try it with and without the springs and see how it goes, As i mentioned earlier this one is just a bit of a play thing at present, I just wanted to get it running so i could at least do a few laps of the yard and perhaps a blockie LOL I never intended to start resto on my Dads one right now, as i have so many other things on the go including being half way through restoring an EH panel Van. now that its dug out i might set it up in an area out of the way, and that can be my something to do when i dont know what to do project LOL The earlier one, i will probably end up moving on once i have had my fun with it . it might donate some tyres though LOL
