The Vapor Fuel System on a 19 77 Volari

i learned, essentially when i was a child, how to do it, and then just learned more. And i invented thisa method of putting a vacuum on the float boll of the carborator so that a slight change in the afloat bull would prevent the fuel from going over into the venturi into the engine. I could gain two seconds on a zero to 60 a a speed test on virtually all the vehicles i did this on. I so i had more horse power waf using less fuel. The engine ran cooler i it was.
