OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Edgers Two Stroke Edgers Atom Edger 410

Hi all, a neighbour dropped off an Atom Edger 410 and asked me to fix it, after inquiring what the problem was - the answer it won't work.

I have not worked on edgers before so am after a bit of info.

What one these 3 choke settings is which?







ps: The old dear also dropped off an electric juice blender that doesn't work but I can't find a thread on it

Hi Buckets,
that looks to be a Ryan half crank engine as used in Ryobi whipper snippers for years.
One question you could ask is how long since last use.
The carby diaphrams can get hard after a long time of non use which means a kit is required.
Check the basics like spark, filter and fuel lines first, before looking at the carby.
As for the choke, A is full choke (closed intake), B partial choke (partially closed intake in diagram) and the far right is engine running position -fully open air intake.

Does this have a primer bulb? If not you fully depress throttle and pull the starter with choke in position A until you hear a pop of the engine, move to B and it should start right up with the throttle in idle, wait a few seconds then move to C run position.

Thanks Mowerfreak, knowing which one was which, done the trick.

I'm pretty sure you are right about it not being started for a while, so I gave it an eyedropper of fuel down the carby and away she went, it runs/idles well.so won't play with the carby, but I will replace the air filter and plug tomorrow when the shops open just to be on the safe side.

Again many thanks for your help.


Now on to the electric juice blender
God Help Us

I'm chuffed my post helped out Buckets.

If the filter is a foam element, you should be able to cleanse it with a squeeze of oil though it unless it's far gone. Foam filter oil is best. Chain bar oil is just as good. This should be done periodically.

As for the spark plug, I never bother changing it unless the motor stops! You can clean it up with a wire wheel as some do but I never do it.

Hi Buckets

MF is on the money, it will most likely need a carby diaphragm and lines at the least. Usually by this age (would be about 25 years old as 32:1 was a later addition), the air filter is powder.

If it is good, the way I like to clean filters is 2 containers - 1 filled with petrol, one with clean water. Dip in petrol, gently squeeze to get dirt out. Then immediately dunk in the clean water and rinse thoroughly.

You can just use soapy water, and this is fine if there is no oil in the filter. But to get the oil (and its entrapped dirt) out, you really have to do the 2 bucket method.

Let it dry

Then as MF said, recharge with bar oil and blot out any excess.

I have about 6 or so of these now and always use 25:1 - you get better protection and even with full synthetic oil at 40:1 there is no smoke difference.

They always smoke a bit - especially the later models with the compression release slot (like yours). Probably poor port scavenging.

Hi Tyler and Buckets,
It sounds like it's ok by what Buckets described Tyler. As long as it's running ok now after getting a kick along, it should be sweet.

MF, I must admit I missed that line haha

With regard to the juice blender, the first thing that tends to go on them is the safety mechanisms that stop them starting. A blown motor is much less likely

As much has I hate electronics, I regularly get tasked with fixing stuff like this

Hi Tyler & Mowerfreak

Marvelous what you miss when in a hurry, just noticed that the primer bulb is cracked right through so that might explain the reluctance to start when cold.
Anyway replaced that and all good now.


Tyler re the blender works fine, I think the problem was the old dear may have run it too long and the safety/overload cut in and it stopped working, so have informed her that it is recommended not to run it for more than 1min at a time and if it happens again, to switch it off and let it sit for 15min before trying again.

Again thanks for the tips.
