I need a ruling on this:
I am a newbie hobby welder. Yesterday, I was fixing up a 21 MTD snowblower. The left wheel was rubbing on the belt guard. Looking underneath I saw that the axle goes through the sheet metal frame where it is tack welded in place. Both tack welds were broken which caused wear on the sheet metal, elongating the hole.
I want to sand off the paint and tack weld the axle back in place. Do I need to drain the gas tank? The welding is on the other side of the machine from the plastic fuel tank. Will "stray voltage" cause gasoline to burst into flames? What about the gasoline that is in the carburetor, does that need to be drained? I don't even know how to do that.
I don't want to go BOOM! but this has always been a mystery to me.
