Here is my latest and likely last Weeden #20 I'll get. I got it off eBay and it appeared to be in really great condition
and complete. However, I discovered the center tank's stack is steel. It had horrid rust through areas where one at the bottom was about the size of a corn kernel! Ugh, Weeden's frustrate me to no end!
After using my Weller soldering iron gun to patch up the larger holes I used KBS Cycle Gas Tank sealer to fix all the smaller holes and seam leaks. Then the normal seal replacements for the sight glass fittings, pressure popper and thread sealer on the piston makes a nice running #20! Actually in the video I talked to long before starting it up and I thought it was going to fly off my desk LOL
I am thinking this engine was made after they stopped making the Big Giant? Perhaps mid-1930s ~1940s engine with all the various brass parts?
