I purchased this Welder from you in March of 2013 and I've had a problem with the hour meter since the first time I Put gas in it. It doesn't always turn on when I crank the machine. I have to let it run for a minute or two then shut it down and crank it back up again to get it to turn on. sometimes I have to do this multiple times before the Meter will turn on. Can you tell me what is causing this? This meter should turn on immediately every time I crank the machine or turn the knob to run/Idle but it doesn't.
