Today I went to look at a used Snapper rear engine rider that I plan on using at my house. It is around 3 years old and is priced about half of what a new one would cost ($625). The mower is in really good shape, the tires and seat look like new. The only thing that has me worried is that it will not start manually. It only starts using the electric start after turning the key 2 or 3 times, after that it seems to run perfect. The engine is a 12.5 Briggs OHV and the mower has a new Die Hard battery. I am wondering if it needs a tune up or if it is something worse. I am also thinking about forgetting about it and just buying a new one even though it is going to cost twice as much ($1450.00) for the same exact mower. I don't want to pay twice as much if it is only a simple problem like a spark plug but I also don't want any headaches that is why I am now considering a new one with a 3 year warranty. Any help or ideas would be greatly appreciated, thank you and sorry for the long post.
