Almost new Ryobi touch start strimmer - will not start after  Winter storage- cleaned plug fuel ratio should be 50:1 I am using 25:1 (as per oil instructions) is that the problem?  any help/tips please.

Usually caused by fuel being left in the machine over winter, which then becomes stale and tarnishes the internal chambers within the carb.
2 stroke fuel can "go off" very quickly so it's a good idear to drain out any from the fuel tank, and then start the machine to run it dry before putting it away for the winter. You may be lucky and get it going without having to strip the carb.....

My dad had mine and left the fuel in it last grrrrrrr, it did start tho with the same warm up time as before, about a week.    I do like this  little machine for working the plot tho.

Thanks Gwiz - had left fuel in over winter, I will start afresh with new oil (synthetic)  and petrol this time with the correct ratio.  Also thanks to Rangerkris.

If you are about Gwiz - I have have replaced the fuel with the correct mix and the strimmer runs OKish.  But there is one more problem - pick up from tick-over to full speed the engine dies even when hot.  If the speed is increased very slowly then max speed can be achieved but the power seems down - bit of tough grass and the engine will stop.

Is the engine running too lean?  Your comments please.

you need to open the "H" screw anti-clockwise a tad (1/4 to 1/2 a turn )

Thanks Gwiz, where do I find the 'H' screw? - only ever had operating instructions, no service instructions.

[Gwiz]

Sorry, I should have said!
On the carburettor there is often 3 screws. One is marked"H", one is marked "S" the other isn't marked usually, but is sometimes marked "T" and turning this one will increase the "T"ickover speed.
The "H" screw I call "H"igh speed,
The "S" screw I call "S"low speed.
I hope this helps

Thanks Gwiz,  have been in touch with Ryobi they are sending foc a special tool to adjust this screw and a diagram where the 'H' screw is.

I'd very much appreciate details of how to get that tool from Ryobi.  My wife's strimmer — she likes the self-start, and can't manage my REAL MAN'S Stihl! — is showing clear signs of incorrect mixture, but I can't get in to the screws to move them.
