Atco 2stroke kick start
Hi all
Just picked up my next refurb project. An old Atco 2 stroke kick start. Can anyone tell me please the mixture for two stroke and should I also use a fuel treatment to protect the valves from unleaded fuel damage. Also I would like to get my hands on a manual and parts list if anybody knows please.
Thanks all

Sorry guys, just my warped sense of humor!
Oh, come on, don't be cryptic
Oh, come on, don't be cryptic, just tell the guy that two stroke engines do not normally have valves and when they do, they will be rotary or reed valves and will not be affected by lead free petrol. It should probably also be mentioned that synthetic two stroke oil shouldn't be used.

Fair point hortimech re my comment, as you rightly say Atco two strokes don't have any valves to worry about plus you are correct in pointing out that modern two stroke oils should be avoided. I am more used to machines that run at 50:1 fuel oil mix so do correct me if I am wrong, the oil to use for the Atco needs to be a very basic non detergent SAE30 oil commonly used in vintage engines.
Totally blind in the fact
Totally blind in the fact these engines don't have valves, so thanks all. So apart from the sae30, is there an oil out there specially formulated for these vintage machines.?

I've been unable to find a manual for this model. I've had success with Suffolk machines I've done and an atco 20inch but no luck with is one and I really want to get it right. Any ideas please?

Hi yes
Hi yes
It says 1755, so I assume it's a 17inch made in 1955

Actually it says 1755/6 which means 17 inch 1955/56.

Quite a lot of Atcos did show the width of cut and the year but your additional 6 has bucked that system. Maybe an Atco expert has the answer.
Ive had a look through my collection of old manuals and Parts books but there’s nothing for a 17” two stroke. It will assist identification if you will post a few images.
Edit. My post crossed with the one from GTC. So there you have the answer.
Manual for the 1755 and 2055
Manual for the 1755 and 2055 model has been on the site for some time. Answers many of the questions in this discussion.

Thats great guys. Thank you
Thats great guys. Thank you all very much.The manual will be a great help. As a newbie I was probably looking in wrong place. Can I download the manual even if I have to purchase before download.
I hope the refurb will go as well as the Atco I recently finished and is now been used by a local cricket club.

Probably 16:1 . Wouldn’t
Probably 16:1 . Wouldn’t worry about the valves , they are unlikely to suffer.
