I had the opportunity to take this 1-day course this week in Wauconda, IL at the regional location of Mack Boring and Parts, the Yanmar distributor for the NE and NCentral parts of the US. My goal was to learn how to reduce my engine maintenance expenses. The program was great for me, as I have improperly done just about everything that I have done and not done some very important items. All of the info was relevant, some very sobering, some gives the confidence to know how to do many things myself - the right way. Had I known how good this is, I would have also regestered for the following 2-day hands-on program where students actually tear down the engines and re-assemble them. I will definitely do that next winter.
