I took mine apart a few years ago because it was stuck. It works , however
in colder temps say 45 degrees when I start the car the rpm is 850 RPM a
few minutes later just backing out of the garage the RPM is 1400 RPM and it
takes a while before it drops back down or closes.
I removed the connector , you have to because if you just apply 12 volts
to the red wire in that connector it powers up the fuel pump. I did this to
check if it was first open and how long it took to close . It does close
but takes longer than what the specs call for. When I had it open to clean
and repair I even set the clock spring so it would have more tension. I
would say with 12 volts it takes well over a minute to close.
I don't feel taking it apart again which is a pain will help. I thought of
finding a way to just add a toggle switch to the red wire so it can heat
it so it closes. I also have a mechanical one that I got from Tram on Samba
that he cleaned and rebuilt and found the proper arm for the throttle
return spring since the one on the electric unit is part of the unit's
base. From what I recall these rely on oil temp and may take even longer to
The main thing is I don't like placing the trans in gear at 1400 RPM. Or
if that's even a concern.
