this may not be a vapor carb / if you do wish to run the engine take your time and get some one who works on them and they will know how
to clean the carb as with any thing that set's it can go bad and old engines some time's do many things . some will rust & lock up / others
may only need the cab clean to run and others may need the points clean as well. check to see if the spark plugs fire / if they do add fuel
check the engine for oil and don't run it for a time on the old oil. hope it is a vapor carburetor
