Ted,
Up is choked and down is regular. By the way, I think the DelOrto engineers
refer to the 'chokes' as "enrichers". The choked carb is really enriching
the gasoline mixture (less air). Probably all means the same unless any
list engineer or mechanic can explain. Also, as you are aware old choke
cables stretch out after awhile (not as often as throttle cables) and
require replacement or adjustment to be sure that when pulled up they are
choking adequately. Also, choke springs need to be of proper tension to
push those choke plungers right on down to the bottom of he carb body.
Sometimes lubing the chokes themselves is useful maintenance. Bob

That is a good question. I think it's right because when the lever has no
tension is when it cranks easily when I pull it back is when it cranks
slowly. When I open the throttle wide it also cranks slower.
When I pull the choke lever (using an old Triumph choke lever) the little
doodads pull up towards the top of the slide in the carbuerator, but to be
honest I have no idea if that is choked or unchoked.

| Ted, When I crank a bike (any bike), if the throttle is closed, then the bike cranks "slowly" in part because it's pulling against the intake manifold vacuum. If I open the throttle wide, the bike will crank faster because now there is no intake vacuum. Is it possible that you've got the choke lever positions backwards? On my ambassador, the choke cable is UNDER TENSION when the choke is OFF, and the cable is LOOSE when the CHOKE is FULL ON. This is opposite to the way it works in other vehicles, and may be the source of some confusion. Let me know how you do. Bill Dudley 72 Ambassador |
