[Roadsters] sticky throttle

[Joe Kinstle]

Try setting the throttle cable length when the car is heated up. When things
heat up, they expand. The valve cover expands away from the carbs, and
vice-a-versa. It doesn't take much to cause the issue you are talking about.

When I got my Dad's 70 1600, he had a extra return spring to pull the
linkage back. I have since been able to do away with this with new carbs and
choke cables. 

Are his choke cables sticking? I had that issue as well before the new bits
were installed.

My son has asked me to forward this inquiry to the group.  His 1970 1600
once warmed up, the throttle is not going down to idle speed.  It seems to
only drop down to 1500 rpm or higher and even with popping the throttle, it
still does not idle down.  He has tried cleaning the linkage with brake
cleaner and then squirting with silicone lube.

 

If he gets out and pushes down the linkage, he can get it to idle down
(around 700 - 800 rpm).  Any suggestions to keep it from running too high
with foot off the pedal?
