I think that its the gas also and recommend what Dave in MN says in post # 6 . The GAV does effect idle unless it is idling lower than I prefer to run mine. The low idle circuit is mostly for showing out at car shows and causes a spooling down effect that hinders gear shifts when idle is set that low. Most ain't gonna run on the low idle circuit when cold or especially if you are running any ethanol, STP gas treatment or other additive that causes the carb to act up . I also recommend Marvel mystery oil in the gas , especially if ethanol is present.
