I was not having any noticable changes with small jet changes so I got some jet drills and drilled out a set of idles so I would have like a 90 size idle jet.
Put them in the car and it drives great with good low throttle response and the sneezing has just about disappeared only a slight random sneez that you cant feel but you just hear. The mixture screws are still different.
When my car was getting painted I removed my webers and I noticed that when you turned them upside down to check the throttle plate to signal hole
gap there was a big difference bewteen carbs. A good carb had the throttle closed and you could not see the signal (progression holes) and the bad carbs you could see the hole, I have just refitted my carbs and later this week will try another tuning session.
