Customer Question

i'm trying to fix a bolens riding lawn mower for my mother it has a 15.5 hp briggs and stratton. she last used it 5 or so months ago.it had a little remaining fuel left over from previous season. it will turn over but not start. seems to have good compression in that if its not well charged it has a hard time turning over. plug had some carbon build up, but has been cleaned up with sand paper. i have added some fresh fuel but did not change it out entirely. it runs strong if i pour the same fuel directly into carb. i took off carb, removed the bowl and inspected float, cleaned it quickly with carb cleaner and compressed air. the carb didn't look to gummy. however i'm getting same result. also oil is fresh and does not have a gas smell. i can also get it to start and run by completley covering intake and then patting it with my hand or slitting my fingers narowly

The carb needs a thorough cleaning. The main jet is clogged. It is best to dissasemble carburetor and put all metal parts in chemical carb cleaner for a minimum of several hours. Then blow clean with compressed air and inspect all the very tiny orifices. This will get you up and running.
