New Hustler Mini Z just bought, and I'm wondering how much I should demand from dealer... - 3 hours logged on engine and it just stopped: carb needle valve apparently stuck resulting in no start, gas smell coming out exhaust. after a couple cranks, engine appeared to seize when trying to start. - Dealer came out to house next day and mower started. I logged a couple more hours on mower and it happened again (engine just killed), this time I noticed gas *pouring* out exhaust when attempting to start and also gas in oil. Most likely gas was in oil when I was mowing that day for two hours. - Dealer has mower and will "fix it". QUESTION: Has permanent damage possibly been done? - engine appeared to seize, perhaps scoring cylinder walls (vapor lock?). - Engine ran for a couple hours, undoubtedly with gas in oil. - Should dealer just check compression? How will I know it's OK? Thanks!
