Question about Ryobi Garden
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?
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

SOURCE: Primer button Ryobi lawn hornet
Vacuum created by piston operation after closing the choke pulls fuel into carburetor port into engine. In much the same way as the primer bulb provides fuel for the port. These type engines usually take a few more pulls before they will start. And if there are any leaks in carb. system will be very hard to start.

I went to www.ryobipower.co.uk, I was ynable to find a lawn hornet on the website. But you may have better luck because in the states we do not have lawn hornets.
