Doing a tune on my Zeniths ,cant find an exact rpm range and done a ton of research ;
Bruce Anderson mentioned 1800 in his book, Factory says 1000 in the gary.suggate site factory manual, Haynes manual tells us 1000. So far I have tuned throats @ idle ,1000rpm ,1400 and 1800 on hand throttle and strangely I get the same balance any way ?. Now thinking its not an issue but would appreciate feedback from 6yl guys with carbs,TIA,cheers |
