Evening again fxxxrr,
Sounds like you’re a chip off the old block!

Sounds like you’re innovation in solving the wheel problem is something your old man would be proud of! 10 points!
Now, the seat problem. I can help you with that. I’ve collected a few seats and seat springs from tractor model machines. They are pretty much identical to the one that would have been on that machine originally. My shout.
Cheers,
LOL i do like a good tinker and problem solve when it comes to shed stuff, In some respects its more fun to try to figure out a way to do it for free, rather than buy something to do the job LOL in this instance all i need to do is buy a couple of tyres and tubes, however that would be no fun LOL i accepted defeat with the carby as i know i had no chance of delicately extracting the damaged tube. wait till you see my exhaust Hack LOL a good rummage through a scrap bin at an exhaust shop yesterday wielded hopefully enough stuff to make makeshift exhaust for either machine if not both, The muffler on the Mk1 machine is barely in 1 piece, and is rather loud, so should decide to keep it it will need something, so i have obtained a smallish car muffler which should quieten it down a lot, For Dads machine i have a rather industrial looking resonator LOL essentially an expansion tube, but will look rather aggressive sticking up like a real tractor.
Im flattered by the seat offer, I need to have a look at the neutral setting on the pedal first, cos if i cant sort that then i will have no chance of using it so no point keeping it, and it would be rather unfair of me to accept a seat only to move it on with the unit itself. although i have thought of adding some separate foot pegs and a lever off the pedal to allow hand operation, My mind sometimes works at a far faster rate than my body will allow me to accomplish maybe i can pay for the seat in stories about my Panelvan LOL ( i do have another old holden and a vintage tear drop camper as well)
