At one point, the secondary boosters were dripping fuel, I learned that's a indication of too high of float level....lowered it and stopped dripping..this happened also with primaries...lowered level to stop dripage. So both as you asked.

I've got torch cleaning tips...and have ran through all passages....if I can spray carb cleaner clearly through passages how is there still blockage??
