ooops...I forgot to close one side of my trimmer rack the other day going 60mph down the highway....hit a bump, and my shindyt242 engine side went scraping along the highway...I bout sh!t a brick. The cylynder wasn't where it was supposed to be anymore....So I had to buy a brand freakin new one...this one only had a few months use on it. Oh and both of my 21" mowers won't start??? replaced spark plugs...don't know what to do next?....Not a small engine mechanic. What the hell...I guess thats what you get when you cut corners and buy cheaper equipment and then try to use it in a commercial setting. I guess I just needed to vent a little. I had a very stressful last week, and I'm thinking this and next..with 4th of july coming won't make it any easier.
