I purchased a new ZTR with a 27 hp Briggs and Stratton Commercial Turf Engine. After just 22 hours of use the engine began surging. The dealer picked it up and serviced it, and said a secondary jet was clogged. Briggs & Stratton considered this a gas issue and would not cover the cost of the service. The dealer was nice enough not to charge for the service, and the mower is not surging since returned, although I have only used it for two hours since getting it back. When I mow, the gas I use I purchase the same day I use the mower from a busy gas station. I used an additive as the Briggs & Stratton manual suggests. Can a brand new engine with just 22 hours use filled with fresh gas develop a surging problem so quickly, or might this be a symptom of a bigger problem?
