I have taken my lawn mower and snow blower there 3 times and each time they blamed the problem on "Bad Gas" Last fall I took my snow blower in and they charged me $60 to rebuild the carb. No problem - I got it home and filled it with gas and started it. As soon as I shut it down gas started leaking from the bottom of the carb. I had to run it for abut an hour to run it out of gas and my garage smelled of gas for about 2 weeks. I took it back and 2 weeks later they had it fixed.
