Okay, the above link is long dead...suffice to say it was a 98% complete TM75 in reasonable condition for $112.50, from near Newcastle. Forum members helped and the bike made it to my shed at the beginning of May.
Here's the update....
Was a bit gloomy weather-wise when I took the pics....
She's rough but runs....
The tank is toast, barnacle size clods of rust adorn the inside, condensation blisters on the inside of the cap. But it turned over and the motor all looks complete apart from the choke cable (and thumb-lever) I took he plug out and discovered the gap closed, I opened the gap and there was spark...amazing considering the lead is some 240v wire inside some clear fuel line and twitched around the plug end.
I replaced the plug and kicked it over...heard a clicking sound and then the kick-starter gave up the ghost. The bolt head snapped and the lever slipped on the spline.
Drllled a small hole into the other end of the bolt shank and drove in an "eazy-out", soon had the thread turning out. Replaced with a fresh bolt and put it on. It's still loose and I can see why the bolt was snapped. The pinch space is already closed and still loose on the spline, over tightening does nothing. It will need the inner surfaces of the pinch shaved a little and the entry hole opened up for more angle.
When I put the lever back on and tried kicking again, the clicking was still there...hmm, I took the plug out and sure enough....the electrode is flattened again. I replaced the plug with a short reach one and gave her another kick....for a missing click.
Sprayed some ether down the fuel line and gave it a kick...she fired and ran about 20 revs....sounded like a scooter. I sprayed WD-40 over everything that should move and eventually both brakes work, clutch and throttle both work and she selects all gears. The only thing that don't work is the choke which is stuck in the on position....I know this coz I pulled the rusty cable and it gave about half an inch and stayed there....
I bled some premix into the fuel line and gave it a tad of air pressure. Folded out the kick lever and gave it a prod...she burst into life and immediately hit about 3,000 revs and stayed there...although the throttle twisted and returned it had no effect on the carby.....3,00 revs braaaaaaaaaaaaaaaat absolutely filling the shed with smoke. This continued for 10....20.....30 seconds, and it doesn't have a kill switch. The 3000 revs didn't bother me but the pawls of smoke sure did....it was rancid. Shoved a screwdriver onto the plug lead to lever it of the plug as it's only twitched on....got a boot through the bars and the darn thing kept running as the lead was still about an inch away from the plug and it arced across. It eventally ran outa fuel and I was shocked.
I suspect the crankseals maybe shot judging by the smell of the smoke.
It's ALIVE!!.......

Cheers,
Chris.
PS: Not bad for the bid price of $112.50.
