Weber Synchronus with stock Kickdown

No not **** it towards the friewall, but make sure the spring axis is not through, or close togoing through, the throttle shaft axis. It is just hard to tell from the angle of the top picture if this is the case or not. Maybe the cable is at not adjusted positioned quite right. Any recent cable lube?

I'd be curious to know how this runs overall and the mielagae, etc.

I just handled lubing the cable and that helped greatly along with titling the spring location a bit. It returns as it should to the set screw. I'm running my first 10 gallon test with mileage to see. Have not gotten to the 10 point yet though to check the first tank mileage. I'll average it out after 30 gallons total.
