I have 2 Craftsman push mowers, both with Briggs 6.25 engines. Both are the later style with no throttle control. Both have intermittently had this issue. On one unit, carburator cleaning as described above resolved the problem. On the other unit, I found that the only way it would run was by slightly loosening the gas cap. (I think this one might have a gas cap borrowed from a junker, maybe not the right one). The clue was, when pushing the primer bulb, there was no resistance, as if there was no fuel at the primer.

Both units run noticably better with fresh gas. It seems like when this crapahol gas gets to be about 90 days old, it does not run well in the mowers, even though the cars still run OK on gas bought at the same time.
