weber carb automatic choke problem
« on: December 30, 2008, 10:26:53 PM »
i have a weber carb with an automatic choke but for some reason the choke wont close I'm thinking i might have hooked up the wire wrong. it is in an 86 samurai, i have tryed all that i could think of and i am running out of ideas, if you can think of something i am willing to try it.

is the wire you hook up hot only when the ignition is on?
is the choke set to be closed when cold? before turning on ignition and warming up that little heater in the choke?
i'm sure you checked for gummed up linkage........
mabe the choke lever is not hooked to that bimetalic spring inside the choke?
one more- there must be some resistance to ground thru the heater element... i don't know the value, but a check w/an OHM meter may show an open circuit thru the element. replacement couldn't(shouldn't) cost much.
i went simple- manual choke.

my theory is that if it's already broke, how bad can i screw it up?
i think you could explore this without doing much damage.
i haven't worked on an electric choke in a long time- some weber documentation could be helpful.
the choke spring/heater is where the wire hooks up. some screws hold it in place and allow adustment by rotating the spring housing. clockwise (i think) should make the choke want to close, as the spring acts against the choke lever inside.
i think you can take it off and look inside as see how it works. heater coil turns on w/ignition and warms up spring which expands and starts to open choke.
does this make sense?
