If you have one of those saws that sometimes needs a couple drops of fuel squirted into the carb to start, this might be handy. I got a $1.00 ketchup bottle from walmart made of hdpe plastic. This is in the outdoor bbq section, not kitchenware. The bottles in kitchen ware are not hdpe. Then i drilled a small hole the same size as a carb cleaner straw into the removeable cap of the bottle and epoxied the straw into it. The straw allows you to reach into the carb and just squirt a few drops. Lots easier than trying to get fuel into the carb by dribbling from a gas can.
