Pulled of the carbs on my engine today to check how the are set up. Only pulled the top on the front carb before quitting for the day but didn’t find stock jets in it so probably need to make some changes, These are correct number 66 carbs and look to be in really nice shape.
I know the stock jetting specs but wanted to see if most owners are sticking with that or some slight modification. The engine seems pretty stock although I’m not sure what camshaft is in it - I suspect a later hydraulic one as it seems too quiet for solids.
I found .083 jets in 3 bores and a single .101 jet in the left secondary bore. Stock is .089 and .1065 so someone in the past has leaned it down. I’ll find out in the morning if this holds the same for the rear carb. My theory on ethanol fuel is that due to its less efficiency as compares to non-ethanol fuel, at least stock jetting or one size richer is generally good. Not sure that’s completely correct or valid but everyone has to have a theory. The car has seemed to idle rich (smelly) but now I wonder if it’s just too lean to burn efficiently.
Curious what other early Hemi owners are running for jets in stock engines - staying with stock jets or something else.
