Leaky oil tank

[Stump Man]

I have several Jonesred chain saws that the bottoms have worned so bad they leak oil out of oil reservior on bottom. What is best material to patch with. Seems to be a weak point. Thanks

Lots of older Jonseys did this when the magnesium correded through. JB Weld is the standard "patch", but try to find a guy with a TIG welder to fix it.
