In one visit, John repaired a problem with my daughter's push mower and my riding mower; both for a very reasonable price.  Besides being a nice individual to deal with, John proved to be very knowledgeable about engines and came equipped with all the tools and parts to do the repairs.  Could not have asked for a better experience and highly recommend him to anyone looking quick and reliable engine repair.

Great "mobile' service. When you cant take your issue in, John will come to your home, and has all the tools and knowlege to fix any of your issues. Awesome, He fixxed my riding lawnmower and went over and above to make sure it was running at peak condition, Highly recommended - and very reasonable. Bill Sullivan - Bel Air Md

I wasn't able to get our generator started. And with forecasts of impending tropical storms, I Googled the closest small engine repair company. John quickly responded to my request - he even came out on a holiday! Got my generator running and was very pleasant to deal with.
