Carb tunning/mod question
crackedback, thanks a bunch for that chart!!!!!!
Picked up a new large/non dampening vacuum gauge today and installed my 2.5 PV.
Twisted the dist ccw until i got my best vacuum, then when a little bit more and could here eng slow as well as vac drop. turned idle down to 900 and was able to use idle mixture screw......they work now, but still not happy with idle quality.
Pulled out timing light and timing was at 30*initial WOW!!!!! Stopped eng and restarted, no kick back.......REALLY? can i run that much initial timing with dist recurved to only have 10* advance???
Anything over 26 didn't change the vacuum gauge much but over 30 it lost vacuum
At 900 rpm I'm running 6 to 7 Inch of vacuum now.
