Hi, I know that is mower is one of the best machines I've ever mowed with for our Lawn,but here in the past week its really been acting up,I pump the primer 3 times and it starts up revs up and down like hi idle then low idle for about 30 to 45 seconds then it dies,repeat same steps and it does the same thing ,to mention the first thing I did was to make sure to have a fresh mix in the tank,then with the same symtoms I decide to break down the carb soak it for a while then I used a can of gumout carb cleaner to make sur it was flush out good then keeping every clean put it back together,then the thing with the hi surging and low idle I've tried to adjust the plactic thumwheel trottle to keep it running so what else could I do to smooth this Lawn Boy down,or how do I adjust it to keep it running. Thanks for any replies of advise to can give.
Ok I took the pilot jet out and cleaned it real good put it back in push the primer 3 times it started and this times without the hi and low surging but it just run a little bit then stopped,so if it helps any I'am going to try to adjust the airvane thumb wheel a little and hope this makes the idle start acting right,BTW is it right just to tighten that piot jet until it just seats or does it work like an air mixture jet,in otherwords has to be adjusted too?
You may also want to take a look at the nozzle # 7 and make sure that both the nozzle and the metering jet # 8 is clean and open. It's located underneath the screen # 9. All parts can be removed from the carburetor by unscrewing.
The thumb wheel # 19 actually puts tension on the governor spring #18 this sets the top no load governed speed of the engine. It is not a mixture adjustment only a speed setting.
Isn't this silver series engine the one with the rectangular shaped throttle box above the carb that warps? I thought it can cause some surging problems

and also the cable slides back and forth to add tension to the govenor spring that controls the idle speed, this box is mounted to the carb with 2 screw bolts.
which I'am still puzzled with how many clicks for it to smooth out the engine,any ideals would help,I put a new air filter in also new fuel line and this time with clamps and a brand new spark plug also new fuel mix with hi grade gas and a new little can of lawn boy oil.

It does not matter how many "clicks" you turn it. It's not going to smooth out the engine. It's NOT a mixture adjustment, it's for setting the governed engine speed. If your engine is not running smooth then there is either a problem in the carburetor, or possibly an air leak.
The air filter box on your engine is not going to cause the engine to surge!
