Is this a stock 206 cu 1936 Chevrolet engine ?
I would wait and
not yank the road-draft/oil fill tube off and burn it with gasoline.
I am no
expert , thus I wonder if the 1936 Stovebolt 206cu engine had a combined oil fill & road draft tube near the generator ?
Also, the wasn't the ignition distributor mounted with a lower set screw and lubed a bit different than latter 1937 216 engines ?
Someone who truly knows the 206cu (nom. 3-5/16"boreX4"stroke) engine is sure to help you out better (and clue me in too.)
I would wait a bit until you get some more experienced comments before cutting anything ... or burning
