My tach has gone out on my 2000 ox66150 I don't really have the money to replace at the moment. My question is, will I cause any damage to my motor if I run it without a tach, I mean it's not like it's an extreme power house or anything, it's just a 150. However, if there are any experts on here that think it would not be wise I'm not gonna do it. Any input is appreciated...
