Anyone know of a good place to get an engine driven welder looked at? I have a Ranger 8. Mine is not welding properly and would like to have it checked out. The fine tune knob only works when on 8 or higher. Im located north of Baltimore in Maryland. Its the welder part of the machine, not the engine. I tried running my LN-25 off of it the other day, and couldn't get that to work properly either. Thanks.
