[Healeys] Cold weather work

[Bruce Steele]

Checking the 6 brass nuts on the flex pipes to manifold are on my annual maintenance checklist.  In my experience, they will occasionally work loose.  I've not had a problem with the manifolds themselves, which are installed as John describes.  

Replacing the choke cable was very straight forward on my BN7 but perhaps access on a BJ8 dash is a bit more restricted.  Gentle "S" curves are the key.  Shooting some aerosol lube down the cable couldn't hurt, I would think.

As I understand the parts manual when I did mine (always questionable) there are 10 brass nuts and plain washers at all mountings for the exhaust manifold, including the ones that overlap the intake manifold. The intake manifold uses plain washers with spring washers and a steel nut.
Have not had the problem of the downpipes coming loose, but have heard others have; someone may have a solution to that.

As to the choke cable; stiffness on mine was due to the brass cam shoe on the carburetor being very hard to move, cleaning and lube helped there.
