Atco Identification and Advice

Good afternoon,

 

would anyone be able to help me identify the Atco mower attached?

I saw one for sale a couple of years ago which had been repainted and well looked after, unfortunately i didn't manage to purchase it but decided to bring one back to life myself.

Where is the best place to start? I need a new spark plug and started rope and wondered if i should clear out any of the other engine parts prior to trying to start the engine.

 

thanks for your help

A few more images from

A few more images from different angles and out of shadow will make identification easier. Also, there would have been a metal tag with som ID data held by one of the chassis fixings on the right had side of the chassis -  is it still there?

OK thanks. I think the tag is

OK thanks. I think the tag is 6221 with an L at the end pressed into the metal.

Atco two stroke ID plates

Atco two stroke ID plates were usually stamped with a number like 1247 designating a 12 inch cut made in 1947.

I don't know how to decode a four stroke with 6221 on it, but OLC member Sir Chook may.

For dating purposes, the engine can sometimes provide clues.

I have a similar machine but

I have a similar machine but it has a different ID

Forum software seems to be intent on putting my text st the end of the post rather than where I put it at the start. This is my third attempt!!

That does look very similar.

That does look very similar. How did you go about restoring the engine? What should I clean before attempting to start it. Even an obvious question..... dor I just use unleaded with some lead additive?

Mine came with the plastic

Mine came with the plastic front rollers but should have wooden ones similar to yours and I added the mesh guard around the recoil starter as there was a potentially finger trapping gap.

Check the oil level in the sump then start by checking for a spark off the end of the HT lead and if you have a decent spark I would then put some unleaded in the tank and try your luck. If it fires and runs you are in luck. If not, check and clean the carburettor .

Unless you intend to run the engine really hard there is no pressing need for additive but a bit of lead substitute, Redex or even just a drop of two stroke oil won't do any  harm.

If you do need to strip the engine or cab, gaskets are available from the likes of the Hailsham Mower Centre and Villiers Parts. 

One thing to watch out for is that back in the day when the machines were in regular use the recoil starter was a weak point and if the engine became difficult to start the recoil units used to suffer. My best advice is to get the engine onto compression, pull the rope gently to engage the pawl / dog and then give it a firm pull. Those recoil units did not put up with much snatching. The process is not helped by the need to pull upward due to the orientation of the unit.  Having given mine an engine overhaul it has very good compression and consequently it is necessary to steady the machine while engaging the starter or it tends to leave the ground!
