Choke staying on

[gingerbob]

Another question for the intelligent ones

Went on a run in the bay (1970 westy - 1600), and the choke seems to be staying on.

At each traffic light/ roundabout I came to it was idling really high, and then stomping on the gas made it idle at a much better speed.

I have had a look in John Muir book and he seems to hate the auto choke and says to disable it - not alot of help!

What can I check to make it happier?

Thanks

1. Check choke assembly casing screws are not loose
2. Check choke unit is correctly adjusted, it may need backing off a bit?
3. Check the choke thermo electrical device is actually working (drawing current)


I'm sure there will be more to come

Cheers - really useful site.

So sounds like something to do with the step cam. Will have to have a nosey later.

If your choke is staying closed this would stop the step cam from opening as the choke butterfly is attached to this.

The easiest way to check you choke is to take the air cleaner pipe of the top of the carb run the engine and see if the top butterfly opens after a few mins.

It sounds like either your choke is getting no electricity, the element in the choke has given up the ghost, or it badly adjusted.
If its adjustment line up the thin line on the choke element body with the top notch on the side of the carb body where the choke element sits.

Is this a problem that has just started? i.e. was the van ok till recently?
