Thanks to all who responded to my carb problems. I finally got the car to
idle smoothly all the way down to 500, but I like 700 better.
I tried every single suggestion resulting in the following changes made after
I CAREFULLY kitted the carbs:
-
Zoz was right about the gasket under the slow idle needle. I removed it
and had massacred the o ring. Half of it was shoved down the threads.Made a
big difference. -
Throttle plate on #3 was not fully closing due to assembly with the shaft
wanting. -
The backlash for the lever arms has to have the lost motion ocurring while
the throttle is opening. -
One of the clips to the throttle shaft was distorted, causing a surprising
amopunt of friction. -
Putting a vacuum guage on the vacuum rail is the way to fly to adjust the
mixture at idle. Simply maximizing the vacuum workes great.
I feel about these HD8’ds the way I used to feel about my Gov Issue .45 many
years ago. I think I can assemble them in my sleep!
Many thanks to all who offered suggestions both on and off line. They were
all very helpful.
