I just picked up a used Toro Recycler 7.0 190cc, it starts fine. Once I get mowing it stalls out, seems to be mostly on inclines. I noticed that if I loosen the carburetor and let the gas drain out, it runs fine for another 5 minutes, then repeats the same symptoms. Engine is a Briggs & Stratton 128M02-0133-F1. I've replaced the air filter and it has fresh gas. Any ideas?
