hho on carburetor.....HELP

[diesel133]

Hi, I am very experienced with making and installing hho generators but have yet to do one on a carburetor engine. What has your experience been with increase in mpg, did you lean the fuel out, and this is a 1985 chevy 350 engine in my dump truck. Any advice, I am looking for advice from people who had experience no backed-up facts. Thank you!

Before you do any leaning I would definately install an exhaust gas temp sensor that way you won't be as likely to damage the motor.
