Update on lawnmower problem

A few days ago I asked about a problem of stalling on my lawnmower and I got some helpful responses that pointed to the carb. I checked for gas flow, and it was fine. Dissassembled the carbeurator and saw rust inside on the float hinges and the float bowl. Funny thing ws the float bowl looked dry (no gas). I tried cleaning the rust out of the bowl, but the hinges were impossible to rid of rust. I checked the float and in the down position gas flowed and when raised it stopped, so it looked ok. I reassembeled the float bowl, and checked that gas was flowing out the screw hole at the bottom before tightening. Reassembled the mower and it would still not work.
Where do I go now? What would be the next thing to check? Or is the problem all in the carb?
Thanks.

Just went thru the same with my generator when the power went out recently. The main jet was plugged. I don't know what your carb looks like but the gas needs to get from the bowl into the throat of the carb. The holes that make that happen are quite small. Be carefull not to make them bigger when you clear them.

If there was rust in the float area that would make me suspect a grain or two of rust has plugged the jet. Carb cleaner doesn't do much with rust but the pressure of an aerosol can might dislodge the rust from a jet. An air compressure ? A couple good blasts might do the job.

Good advice. You've got to finish the carb cleaning, ensuring all the crud has been removed and all the passages are clear.
