Divorced choke

[Bradley D.]

Had a bit of trouble with the choke working properly on my 327/350. I have the
3810 holley with the divorced choke.
The choke rod that goes from the
bi-metallic coil up to the cam/lever that moves the butterfly closed was about
1/2 inch to short. Too much to re-bend the choke rod and make it work. Couldn't
get any parts supplier to tell me the length of the choke rod, only that they
have only one for that carb.

I went to the local hardware store, got a steel
rod of the same diameter and with some bending and filing got the exact length I
needed to let the choke work as intended. Whew.

Anyone have a similar problem or know why mine seemed too short. I am using only one gasket. I have original
type/style 3810 made post '72. Pictures of the carb around(froums, etc) are
identical to mine.
Its just a puzzle to me. I'm okay now, everything works
on the carb.

There was only one original choke rod for your application and it was GM #3881888. It was discontinued in July, 1968 and replaced by GM #3917616. The latter was discontinued without supercession in March, 1997.

So, why is the one you have too short? I can think of a couple of reasons if your carburetor base gasket is the same thickness as stock. First, it might be that you have a 3917616 replacement and maybe that one is not really a good replacement for the 3881888. Sometimes this does happen. The second possibility I can think of is that you just plain have the wrong rod.

Fabricating an auto choke rod from rod stock, either steel or aluminum, is pretty common, though. I've done it many times for one reason or another (e.g. using non-stock carburetors, using non-stock intake manifolds, using non-stock choke stoves, using a different thickness carburetor gasket, etc.).

Well that pretty much kills my idea of a new business venture. Glad to see I was not totally all wet.

It's too bad they don't relate each of their part numbers to original OEM part numbers.
