Rough low throttle on Lawnboy Dura Force Pro 6.5

Typical for any carburetor is 1 1/4 to 1 1/2 turns (out). These are just rough settings to get the saw running. Remove chain, turn idle throttle speed screw in to increase idle rpms so its less likely to stall. Follow mfg instructions for starting.

Once running, adjust low speed mix and allow a couple minutes to warm. Then re-adjust low speed and lower idle rpms by turning out idle throttle speed screw. Then with throttle wide open adjust high speed mix. If saw hesitates from idle to full throttle, open low speed mix 1/8 turn and readjust high speed mix.

If saw doesn't fire in 3 or 4 pulls remove plug. If plug is dry no fuel, if wet either no spark or idle mix to rich (or fuel metering may be fouled).

start emegency call 911 and during connecting try to push message button when comes just put *#4363#*#* and press back button this will put you in setting now open about tap 7 times buildernumber now step back and open develper option and enable oem unlock.

I would think that the screws have limiter caps, so you cannot turn them all the way in.
1) put both screws at the maximum you can turn them out
2) start and warm up the engine
3) at idle speed, turn the L needle in till the engine speeds up (by itself) and then starts to lower rpms.
4) from that point, turn the L needle back out till engine raises and then lowers. Leave the screw in a setting that the engine sounds a little rough
5) use the same procedure with the H screw (at full throttle)
6) now throttle up from idle
does the engine pick up quickly? settings are good
does the engine stumble and then finally begin to pick up?
Then turn the H out about 1/4 turn. If needed for rough but smooth running, turn the H out again another 1/4 turn.
*Please Note: 2cycle engines should ALWAYS sound just a little rough at full rpms. NEVER adjust a carburetor so that the engine 'screams', you will not have an engine for very long at that condition.

It is a Dura Force engine made by Lawnboy,not a Tecumseh.I have the same mower,and that is the info,I am going to use to file my claim.
Good Luck

is the deadmans handle pulling the cable enough to cancel the off switch? if not relase the cable from the handle, TIE A KNOT IN IT(!), re fit to handle, & bingo!
If the cable is working well enough already DONT tie a knot, it wont help, its the ignition coil! ( around £30)

TORO ACTUALLY OWNS LAWNBOY , MOST ANY TORO DEALER SHOULD BE ABLE TO HELP YOU

First remove the inline fuel filter in the tank and replace it, before adjusting the carburetor. Also Be sure the linkage from the governor and to the engine has not broken or fallen off, next check the fuel pump bulb by removing the air cleaner and pushing the bulb in if you see a stream of fuel each time you push the button it's fine otherwise the check valve may be dirty and you will have to clean it to fix the problem. Also make sure the air cleaner is clean. After you check these items then you can adjust the fuel mixture screws turning the air mix valve firs and getting the motor to smooth out at low speed. Turn 1/8 of a turn at a time till you get the desired running range. Also check that the spark plug is nor dirty if it is clean and re-gap it if the electrode is worn out then replace the plug.

take the air filter off the spring is attached to the govenor rod to a fixed arm once attached the arm can be bent to tighten the spring or bent the other way slow the speed tighter the spring faster the speed there is another rod attached to the govenor rod to the throttle
