I have recently replaced old fuel lines. Now the engine will only run if I have Choke on.
There are 2 adjustment screws on carburetor, I assume one is to adjust Fuel flow and the other Air mix. The question is which is which and How do i adjust them properly?
Experienced gardeners share their insights in answering this question :
Hello sir,, now there are two types of carb.adjustment screw covers,the old one where there are plastic over the screws,simple remove the plastic covers with a pair of needle nose pliers or cutting off,,,second are the new ones that are above the adjustment screws,which you have to take your drummel tool with the cutting blade and cut slots in the screws, after you get this done it is important to count the number of rotations in until stops make note how many. because you are going to reset the same way.now remove the screws,put to the side when you get ready to put screws in put in all the way than back out as many turns that you noted, now that is factory set there should only be a small adjustment to do. the rule of thumb is turn both out 1 1/4 turn and adjust in until saw runs smooth and idles ok, it is hard to adjust the top speed when saw is running wide open,let saw idle when adjusting top speed is easier that way, when you go to cut wood you may have to readjust top speed, the above does apply some what if you are not using fresh gas mix and dumped out the old fuel and starting with fresh,and a new plug CJ8Y,and as you know the saw has to breath in and out by this i mean a clean air filter,make sure the small screen on the muffler is not cloged,this will keep saw from running at peak speed and sawing wood, ok i have ran across a few saws to where the small screen in the muffler is cloged so the saw would idle but not run at high rpm’s,if you do and check all of the above your saw should run,oh btw check compression should be above 60 to 160 lbs, hope this helps,any comments welcome,please accept my solution,thank you. 00

Ensure that the fuel you are using with your Ryobi is the correct mixture of gasoline and 2-cycle lubricant if the engine sputters or smokes while in use. The mixture should be 50:1. If it isn`t, let the engine run until all fuel is used in the fuel tank and fill the tank with the proper mixture.
That first number is the amount of fuel, the second part the two stroke oil. Most power tools work on a ratio of 25/1, so that means you need to mix 25 parts fuel to 1 part two stroke oil. Once done so you then pour that mix into the fuel tank of the unit.
Mix the fuel at a ratio of 1 part 2-stroke oil to 50 parts petrol, in a clean container approved for petrol.
Set idle speed adjusting screw, clockwise to increase rpm, counter-clockwise to decrease rpm. Idle rpm range should be 950 to 1050 rpms. Adjust idle mixture by turning idle mixture screw slowly clockwise until the engine runs poorly.
Downstream of the venturi is a throttle (usually in the form of a butterfly valve) which is used to control the amount of air entering the carburetor. In a car, this throttle is connected to the vehicle`s throttle pedal, which (along with the brakes) is the driver`s main method of controlling the car`s speed.

How do you get the fuel line connected to the fuel filter nipple on the bottom side of the gas tank on the Ryobi 725r gas trimmer?
You must run the fuel line through the back of the tank and out the filler hole,make your connections,i used a small amount of vaseline to make the connections.Then pull the filter into place,make sure some of the nipple of the filter pokes through,then slide the retainer ring on the hose and force it onto the filter nipple.
