Have a ryobi ss26 weed whacker and having a problem getting it started.. the instruction manual is missing and after priming the unit, moving it to full and trying to crank it, it will not hit and when it did one time, went to full and it cranked, worked for about 5 minutes and then when tried to restart it, no luck when i repeated the steps taken before.. Is there a set starting procedure to use?

I got on here to find the solution for the same problem. This seems to be fairly common. I need to have it at 3/4 choke to run properly. Other posts say the exact same thing, about the 3/4 choke. It is apparenly something that breaks occationally.

I'm going to remove the carb and take it apart. My suspection is the diaphram in the bottom of the carb. There isn't much you can do with the carb, it is very simple and has few parts.

There is a chance that it is a blocked passageway also.

There are instructions for adjusting the mixture, but they are not clear enough. I will be posting a clarification reqest on one of those posts. Will also post again after I check the diaphram.

SOURCE: Hedge trimmer starts fine then stops after 5 minutes

Carburetor high speed adjustment ( screw nearest the filter ) open ( counterclockwise ) 1/2 turn.
Adjust again as needed to run when hot.
make sure the gas mixture ratio is as required.

SOURCE: Hi, I have Ryobi weed trimmer

Try adjusting the L and H screws on the carburetor.

Hiya
The Ryobi website has a lot of current models for viewing, and many of them also include service manuals.
The website is promising to make available an archive of the service manuals of discontinued products.
I have found that online directories promising quantities of service manuals for download, require membership, membership payment and then informs me that the model I am looking for a service manual for is one of the few that is not in their extensive collection.. Each model I am looking for is not in their extensive collection.
I would recommend that you view the available service manuals from Ryobi and see which is a closest match for your product and see what they advise. The manuals appear to be quite simple, and do not promise much in the way of servicing information, other than regular oiling of moving parts such as blades.
I hope that this helps.
