Methanol burning 084 rebuild

[Brewz]

Howdy folks.
Last weekend, I picked up 3 x 084 saws.
One is a runner, 2 are rebuilders.

One of them is special.... a bit like me

I am starting this thread to keep it updated on the rebuild and also in the hope that someone on here may be able to recognize the work to assist me with tracking down who built it.

Its very well built, and has done bugger all.
Speaking with @Postrip tonight, he said it has a 3120 piston. The piston looks to be free porting on one side at the bottom right of the exhaust port and something has gone through the top end so Id say something has gone wrong.
Otherwise, it loos nice.

It has some numbers stamped into the front of the cylinder that I will get a photo of tomorrow
Pipe has been braised together, cylinder porting looks VERY tidy.
transfer bridges are no longer.
Intake has been welded up and has a modified HG2 (I think from memory?) carb fitted, not a HT tilly.
It has a very intricate hand made throttle arrangement that may lend some clues to the builder

As I plan to try and get it running and know NOTHING about alky saws, I would also love to hear any advice or info on fuel and saw setup etc.

Subbed going to be a cool rebuild.

That looks like it'll put a smile on ya dial when put into wood. Not many junker builder saws have such sophistication!

At this stage, I am most interested in the fuel and what to use.
The nuts and bolts are easy

Very cool project can't wait to see whets going to happen with it.

Im thinking I might widen the exhaust a bit and give it a muffler mod haha

If ya gonna run alky...16-1 minumum on oil...and make sure it mixes with alky like klotz kl200 or benol

Very cool Brewz...I picked up a modified 3120 out of OZ quite a few years ago. The work was immaculate but it wasn't a two-piece head. It came out of Tasmania from a long time logger there.

Damn that thing is sweet! Someone's put some serious hours into that, can't wait to see it run. Why do I never find things like that?

I have benol!
Do I run strait methanol?
I have read talk of blends of different fuels

 

[Chainsaw Jim]

Probably be a better build on gasoline.

 

[Brewz]

Local hobby shop sells some premix fuel for nitro RC cars

Any preference between KL 200 or benol?

 

[Brewz]

Probably be a better build on gasoline.

Why is that mate?
Interested to hear your thoughts.

Compression will give you a I'd to whether they used nitro or not. It's abig pain to get it to work but when you make a run that sounds perfect it keeps you chasing it

A little free port won't hurt anything. My solo freeports pretty good and runs damn strong.
