carb tune info

Id start by checking for vacuum leaks and verifying the timing curve

Id start by dropping or raiseing the fuel pressure to 5.5 lbs and verifying your getting a minimum of a 1/2 gallon a minute unrestricted flow

Id start at all four jets #70

Id install a NEW power valve and ID buy several,if your carb uses them, so I could play/exchange/test


start here, theres no sence in guessing

heres where
a infared non-contact thermometer helps diagnose mixture problems very quickly, but youll need one that reads into the 1400F range for the headers for quick diagnoses

http://www.professionalequipment.com...qx/default.htm

temperature range from -58 to 1832F

I use this one :grin: (above) and youll need to learn how to read plugs (this may help)
