So after a mate gave a recomendation I bought this
http://www.gumtree.com.au/s-ad/redb...ield-tractor-mower-new-engine/1086079808It has a new engine and every thing mechanical is pretty rock solid*.
body needs some love but the chassis is pretty much dirty with small paint chips.
* I have found a few little problems (steering wheel is loose on the main shaft and the new engine exhuast is just alittle to big for the front cowl)
I have worked out the exhaust....making a straight pipe with a go kart muffler at the end, the sterring shaft is where I am a little stuck..so if nay one has any advice, I'm all ears
Cheers Peter
