SOURCE: what are the carb settings for ryobi rct 2800 cb trimmer ,they have been adjusted so the correct position of the screws is not known

Hi peter beaufoy...
Before you remove or try to adjust your low and high speed jets you should always count the number of turns it takes to lightly seat the idle mixture screw and high speed needle adjusting screws.
Be sure to write the number of turns down on a piece of paper so you will know how many turns from the seated position to open the jets when you go to reinstall them, or if you remove them for cleaning or replacement.
If you have aready tried to adjust them then the adjustments below should get it running for you for final adjustment when warm.
Normally you will adjust your idle jet to 1/2-3/4 turn open from the bottom seated position.
Then you will re-adjust the low speed of the engine when the engine is warm by turning the idle screw in or out till the engine runs smoothly at idle speed, around 1200 RPM.
The high speed jet is adjusted to 1 1/2- 1 3/4 open from the bottom seated position, after the engine is warm.
Then re-adjusted by turning the High Speed jet adjustment screw in or out till the motor runs smoothly at high speed.
Alway use the "lightly seated" method if you have not changed the screw settings.

Hi what is the ratio of oil to petrol on the 26cc petrol strimmer


Usually on a 2 cycle engine I will use 32-1 mix. Most engines will be fine if you get a name brand oil like Ryobi, Still, Echo, etc, with a pre-measure area made on top of the bottle. Follow instructions (usually 2.6 ounces per gallon.)

Ryobi rlt 30 cesa petrol strimmer will not start


Keith you have got to make sure the gap is right between the coil and the magnetic flywheel. Use a buisness card to set the gap and make sure the coil is on the right way.

I've lost the user manual for my Ryobi 25cc RPT 2543c strimmer. Can you please advise where the dip stick is to check the oil. Can't seem to find it.


Ryobi RPT 2543c This is a 2 stroke engine, so no dipstick. You mix oil with the petrol (ratio 50:1) or 200ml of two stroke oil per litre of petrol, and that's how the engine is lubricated. Hope this helps, arvidis@btopenworld.com

Mcculoch mt 300mcculoch petrol strimmer carb two adjustable screw bolts ones for petrol, ones petrol & air mixture hich one does which


Actually both screws are for petrol mix. The screw closest to the engine is the Lo side. Lo side jet provides petrol at idle and during the ramp up to speed. Hi side jet (closest to air filter) only effects the mix at high speed.
From McCulloch, these were set at 1 1/4 turns out.
Good luck!

I have been given a ryobi 306rt petrol strimmer. It starts and then cuts out, I'm not sure of the exact settings as to how you start it up and keep it runnng. Any help would be apprciated.


To give the inital fuel needle mixture settings i would need to know the type of carb. on the unit ie. zama,walboro ect. it should say on the carb.,it may take a little hunting for. Second check all the fuel lines running from tank to carb. checking for craks or breaks.
