OK Sphere, than maybe you can offer some info?
Engine starts fine, idles great at lower speeds but you put it under any load at any speed or increase the throttle to a higher speed and it dies. Seems to be a governor problem but I'm not sure beyond that?
Engine has about 100 hours on it.
Thanks
Mike
Gummed carb. Every problem on a B&S is due to a gummed carb.
Yup, clean the carb, and check for grass crap caught in the pick up screens.
Also, make sure the tank is clean, and some have a secondary tank in the tank, check that too. And make sure the little gaskets aren't cracked. Fresh gas too. Blow out all the carb passages with carb cleaner.
Fresh plug and you should be good to go.

Did all the cleaning carb stuff. Pulled it and cleaned the needle and seat as well.
Any thoughts on the screw adjustment. On a car I've always adjusted for best vacuum at idel. How 'bout these little guys?
Mike
pull the filter from the end of the fuel line in the tank?
screws are at idle..crank in till starting to sputter..then back off 1/4..the other screw is idle rpm..it bears on the throttle adjust. Make sure the spring is hooked to the Gov.flutter...
cracks in the fuel line?

Had a car that acted the same way. Ended up finding a crack in the riser between intake manifold and carb which let too much air come in at higher rpm. I could adjust it to idle but would not run under a load. BT
It has nothing to do with the governor. All the governor does is open the throttle.
Do you have 2 mixture adjusting screws? Sounds to me like the idle speed mixture is adjusted correctly, but the high speed isn't. It's starving for gas when you open the throttle.
I'm far from an expert on the subject, but that's a reasonable guess.Give a man free hands, and you'll know where to find them. [Mae West]
BH,
I have only one screw and its the one that holds open the throttle butterfly that is in turn connected to the governor linkage. Thats why I thought they might be "connected?"
Maybe not huh?
Mike
I do actually kinda do this for a living. sorry boss hog but the governor actually does do more than "open the throttle". But he's right its not your problem. It is most likely a carbueration problem as most have said. the normal start up settings for your jets are 1 1/4 to 1 1/2 turns out. The two places that I would look at would be float hieght adjustment, and for an air leak at intake gasket. It would help a little if I knew what its application was. You can get Briggs and stratton repair manuals at alot of places probably even get one from your local library.
Its a mower, 11HP. Like I said, idles beautifully but put it in gear drive it 10 feet and it starts to putter and then die. Restarts very easily. But does it all over again.
Mike
If you have replaced the fuel filter, then I would check float level next. sounds to me like the float sits too low. Its hard to diagnose without seeing and hearing it.
I read about a problem like that in a science fiction novel just last week. It was an ultra-light aircraft that would idle but not run at full RPM. Turned out there was a complicated mechanism in the gas cap to keep it from leaking in inverted flight. The complicated part got jammed, let enough air into the tank at idle, but couldn't keep up with the fuel flow at high RPM. The fix was tearing out the complicated part and refraining from inverted flight.

Here's another forum that's just on small engines. The advice there is probably not any better than what you would get here.
