Default Jensen Interceptor 440 - Help needed!!!

... and not just cos we bought one.

I suspect the ignition timing is miles out on it, runs well above around
1500 rpm, but is rough as hell below. Sounds lovely, but it's a bit
disconcerting when it spits flames through the carb when I'm trying to start
it... starts first time when cold though.

The engine has had a full, *mega* expensive rebuild, and the whole bloody
car has only done 16,900 miles from new anyway.

Problem is, I don't really want to do the timing by ear and guesstimate it,
so does anyone know the correct procedure for setting the timing on one?

Set to how many degrees, etc, at what speed idle?

Ta!

Ah, high maintenance vehicle! :-)
I never had one but always wanted one although I did have a Jensen Healey. I
found the Jensen Owner's club very helpful (and I don't like clubs!) and
better still, the Jensen mailing list.
Unfortunately, they can be pigs for reliability which put me off, but I
suggest you get a good workshop manual and keep it near the car! :-)
Sorry I can't tell you about the timing etc, but it is a Chrysler engine so
the yanks on the mailing list would be the best source of info. Is the 440
the same as the SP with triple carbs?

In the days of the wooden boilers,the clever clogs at this time decided that
there were 360 days in a year,so the world was devided into 360 days or
degrees,and this method is still in use today for measuring or dividing
circles.just think of a clock face,it is divided into 60 minutes, so
360/60=6 that is each minute is equal to 6 degrees. tdc is marked on the
pully so set ignition to 2 minutes to twelve, final adjustment on the road
test.

Unfortunately not. All the convertibles had the lower power 440 in.

This one has had the Carter 4 barrel replaced by a rather huge Holley 750
double pumper on an Edelbrock manifold though, so it shouldn't be far off on
power.

Around 330 bhp I believe.
