I have an old Lincoln weld with a 2 cylinder Onan engine on it. I have not started it in 4 plus years since have had no need for the portable welder. Well a friend called today and said hey I need you to come over to my place and do some welding for me. I told him shoot its been years since have started it up. Well I went out and uncovered it and check how well it would turn over. Poured a little gas in the carb and pulled the rope 3 or 4 times and it fired up and ran a minute or 2. So guess it will not take much to make it run well. Just wish I could figure out a electric start for it
