Advice on leakdown tester
I went to the dealer to order a new leakdown tester and I was suprised when I found out that one from Kohler is $150 and one from briggs is about $170. I went to another dealer and he had a brand new Kohler tester that he just got in and he said he would let me have it for $100. He also had one from Stihl that was about 3 years old and he said he would let me have it for $40.
So what i'm asking is should I get the new one or the used one. He said Stihl would test 2 and 4 cycle engines but the Kohler would only test a 4 cycle.
