I have contacted both the Technical Service Representatives from briggs and stratton and the Chief Executive Officer Mr. Teske himself and it seems no one at Briggs and Stratton cares about a serious problem with their lawn tractor engines. I purchased a MTD lawn tractor with a Briggs & Stratton 17.5 H.P. engine installed in it. The lawn tractor wiring going to the engine has caught fire once and it was repaired. Then 2 months later the unit started spewing gas from the carb while it was in operation. The carb was repaired, and I used it for approx.
2 months and it occured again. The carb was replaced this time with a new one. Then the unit started backfiring on a regular basis and then I noticed that the carb was spewing gas again while operating the tractor. It has done this several more times. Although Briggs & Stratton have been gracious enough to replace the engine at their cost, they continue not to address the problem of the faulty engine and the hazard it might present to others. I have no way of knowing if this is a one time problem or if it is a major problem. My concern is that someone out their will get seriously injured from this. What I did gather from Briggs and Stratton is the fact that they even say in their trouble shooting website is the fact that, and these are their own words "Some Cargburetors can induce bacfire due to the sensitivity of internal transitional passages. This condition cannot be corrected." It seems then they are admitting they have a problem with no way to correct it, but you know I might be wrong, but that's there own words. You can find them in their website under Answer I.D. #1384 and as well you can read that they say that "backfiring or Antifiring does not hurt the engine, yet they ask you to check for an "anti-firing selenoid to see it it is operating right." My qestion to them is "if backfiring doesn't hurt the engine, why do you have an anti-backfiring selenoid on the unit, doesn't that run up production cost on the engines in the long run when they aren't needed?
