About

I repair neglected power equipment. This channel was started because I found a lack of good content regarding portable generator repair and wanted to document some of the things I came across to help others dealing with similar issues. These videos are detailed and long, but would rather leave the details in to help those who are learning. Do what I do at your own risk. Generator voltages are lethal. Small engines can cause serious injury. Gasoline is explosive and moving parts can cause serious injury. Always use power equipment outside. This is not an instructional video but meant for entertainment. I am not a trained small engine professional or certified in generator repair. No information contained in this video shall create any expressed or implied warranty or guarantee of any particular result. Any injury, damage, or loss that may result is the sole responsibility of the user. If you want give back, use PayPal: https://www.paypal.com/paypalme/jamescondonYT

Video Description

It has been a few years since this bike last ran. According the owner it did not run that well. It has the usual fuel problems and a lot of electrical issues. Lets get this bike back on the road.

Harbor Freight changed the recipe. The bottle previously stated "NON-CORROSIVE". Now it says "CORROSIVE", "do not user on Aluminum". It now damages most carburetors.
