It was a twin 272 , it was at a few races up there . It ran I think at Lake City when I was there , it looked like a hand full to run but if all bugs worked out and setup correct it should be pretty fast

EJ had twin 272. The one above is twin 3120. You can clearly see difference.

EJ's pic of twin 272

Twin 272 on pipes, raced against it a couple times . If it had a good chain on it it may of been hard to beat

Thanks Niel, love your story about this twin hotsaw

thanks mate, unfortunately back then footage was not taken so finding actual footage is hard, I know I have more runs somewhere and should find them for viewing.

Neat footage to watch. I just couldnt imagine trying to handle that twin.   :o

 Thanks for taking your time and finding this for me.   8) 8) 8)

Thanks Kevin, that was a fairly ordinary run I thought, but that was its early days and running that heavy  bar and chain was a handicap.
Once I cut off an Oregon bar and drilled / regroved it etc. to run 14 tooth in 3/8 it became very hard to beat then.
The problem then was keeping the chain on the bar, as it stretched the chain to the sh*t house.

some old footage of my twin 3120, running 3 cuts in hard wood. (sold off years ago to another race mate)
here a semi final then the final of Open Speed at Bermagui in the 90's.
It was set up to cut 20inch hardwood, single cut but I found it could run in open speed events as well.
Hence that horrible harvester bar and 11 tooth sprocket running 404, I replaced that and run modified bars in 3/8 and 13 /14 tooth sprockets, which made huge gains in speed.

In that final the winning saw was a Stadler built 084 (USA), and was considered the fastest saw in Australia at the time.
