Unit has been in storage for 4 years, It ran but leaked when I put it away. I bought 2 Yongs Hengs so didn't need this anymore. Took it out this morning to take pics and it wont turn on. I think it's the switch. Anyway if you are looking for a parts machine or a project, this would be a good one. I have several extra orings to rebuild the pistons. The parts are worth the 200 I'm asking. If you own one you know parts are hard to come by now that they are out of business and no longer offer parts.
