Thread-topic: tuning, part 2
Yeah, that was my suspicion. But I thought I'd try it anyway, since it
is electronic. We tight and all. ;)
 
I've already plugged the vac. port on the rear carb, using one of those
red "Help!" packages of rubber caps.
 
I do have a Mallory DP in my stash of parts. Guess it's time to buy a
cap, rotor, points, and the advance curve kit. (about $100 for all that
stuff...) The UK spec advance curve is in the Bently book, so given that
I should have a better starting point.

Gotcha! 

Ok...in any event the US spec. distributor 
is neither compatible or suitable for your 
application then... 

There is however, a way of using yours 
as strictly a mechanical advance unit until 
you can get your hands on a European 
spec. type. I would assume the Triumph 
list would be a good source for info on 
the "correct" distributor for your converted 
carb application. 

Block all vacuum ports to either carb or 
intake manifold. You may have "holes" in 
both places. Normally, vacuum retard is 
ported to the intake manifold, while vac. 
advance is ported to one of the carbs. 

Your carb. set-up is Euro spec, so no 
doubt you'll find a vac. port "barb" on 
one of the carbs. rather than the intake 
manifold. Whatever...block 'em. 

Statically time the distributor in at 10-14 
degrees BTDC. That's it. This will give 
you a total of 30-34 at the crank with a 
reasonable advance curve. 

If you want to time it dynamically, time 
it for "total advance", wherever in the 
rpm range total advance is reached. 

Anything between 30-34 total advance 
will work until you can get a more suitable 
unit.
