It idles fine at about 850 rpm, drives fine when just putting up and down my buddies drive way. Yes: backed idle screw out till no contact and turned in till i just made contact and about 1/2 to 1 full turn in beyond that. Then by "conventional" weber tuning methods decrease primary idle by 5 for every 2 thousand feet above sea level beyond roughly 2000 ft mark. which should put my primary idle jet at 50; 10 below stock setting which is a 60 primary 50 secondary idle. Problem is in order for me to achieve best lean idle condition with 60 pri idle jet i am 6 to 7 full turns out on idle mix screw, which by weber tuning i am too lean. I need 1 to 2 full turns out on mix screw which i can only achieve by having NO IDLE JETS at all. i have every idle jet made by weber for this carb both primary and secondary. even with 95 primary ( biggest made by weber ) idle jet i am still too lean about 3 to 3 1/2 turns out on mix screw. Conditions with carb set like this: PI 95, SI 80: PAC 175, SAC 190: PM 120, SM 180: APJ 50. Idles fine, crack the throttle from idle hesitation then picks up, stumble at about 2300 rpm up. Goal remove hesitation when cracking from idle and remove stumble above 2300. from what i was reading all stumbles and hesitation are from not enough fuel. so i removed all idle jets hesitation virtually gone when cracking throttle from idle. so was thinking i will try this tomorrow decrease air correctors to hopefully richen up and increase main jets to see if stumble goes away.
