Replace Gold idle screw on the carb and then keep turning it clockwise till its revving high, Then slowly do it anti clockwise till its idling at a low RPM which you feel right or/and defined in the owners manual.

Ryobi 725r trimmer carburetor adjustment


Turn both low and high adjustment screws carefully clockwise all the way in - do not overtighten.. Then back out each two full turns. Set the idle speed control for highest setting. Prime and start and let it run and warm up for about 15 seconds - then lower the rpms a tad and then adjust the low end screw for highest rpm. Then reset the idle to lower reasonable level. You may have to go back and forth with those two adjustments till it runs fine at low idle speed..

Then accelerate to highest speed and set the high adjustment for highest rpm. Then go from idle to high speed. If not smooth a small adjustment on the high speed screw is in order. Keep doing that until you get a nice smooth transition form low speed to high speed.

91 jag xj6 setting idle mixture


screw both screws in until they just come to a stop. One screw should have the letter H and the other screw should have the letter L stamped on the carburetor next to each screw. Once you have both screws turned in until they stop. It doesn't matter which one you back out first. If you do the H one first then turn it out approx 1 1/8 of a turn, the the L screw back that out approx 3/4 turn. Those are the initial factory setting. Now you have to fine tune from there. To finish fine tuning the trimmer work on the L screw until it idles smoothly and then set the idle screw to a speed when the head just starts to want to turn over. Once that's done work on the H screw by reving it up and keep it full throttle while you adjust the H screw in or out until you fine that nice high speed. then slack of the throttle and see if it still idles, if it does now give it a quick throttle up to see if the response from low to high is a smooth transition. If it bogs on the quick throttle then you need to open the L screw a small bit more and re adjust the idle screw. Good luck

What is the factory setting for lowand high screws on 25cc craftsman blower


If the two screws are side by side, one is the high speed mixture screw and the other is the low speed mixture screw. To set the high and low adjustment screws, tighten the screws in until they stop, don't force the screw after it stops. Back each screw out 1 1/2 turns. The engine will start and run here if everything else is ok. Fine tune each adjustment screw by closing the screw off (CW) until the engine runs rough. Back the screw out (CCW) until the engine smooths out. Run the engine at full speed and adjust the high screw. Let off the trigger and adjust the low screw. Once the mixture screws are adjusted, you can turn the idle screw to adjust the idle speed. It can take some time getting it all adjusted.

My truck starts and stalls and will not idle


Try increasing the idle speed. If you don't know, this is how to do it.
Open the bonnet and ask someone to push and release the gas pedal a five second intervals.
Observe which part is moving.
Yo will see a small adjustment screw on that lever. You will understand that by adjusting the screw you can increase the gas supply to the engine.
Slowly rotate the screw while the engine is running. (If the engine doesn't run in idle state as you have explained, ask someone to keep the pedal slightly pressed. After increasing the gas supply, ask the person to release the pedal).
Adjust it further to get a smooth running condition at idling.
Also check whether air cleaner is blocked.

After running for about a half hour or so it begins to stall in between cuts . . should i adjust the low,high or idle screw


Is the chain being properly oiled? You should get a thin line of oil after running the tip of the saw near to a piece of paper or cardboard for moment or two. Is the saw getting overly hot after running? Clean the cylinder and air passages with compressed air if it is. Check the muffler for any plugging of spark arrestor screen. Turn both jet screws CW to stops (lightly) then turn both out 1-1/2 turns CCW for a basic setting. Pull throttle full on (after warm up) and adjust H for high engine speed, but 4-stroking that smooths out immediately when cutting. Release throttle and adjust L for fairly smooth idle, but rich enough to allow the engine to 'follow-the-throttle'. Adjust idle speed so that the chain stops moving. Hope this helps.
