When you first displayed your new toy you mentioned "twin
carbs". In my Triumph ignorance I must presume they are not
standard, and therefore a potential prob if not properly set up!
What carbs are fitted, of what size, using what needles and most
importantly of what degree of wear?
You have got to presume that the prob is too much air in the
mixture - you know that, it is obvious. But, that is firstly
displayed by what you mean by it runs with choke. Does it run
almost normally, or lumpy and 'orrible. Does it fire at all with
the choke off?
More info required!!!!!
Also, I find that things with rooves and 'eaters go better (fuel
injection don't youknow)!!!!!
FF.

There is a roove and a eater in the garage so that can't be it.
Trying to research carb settings books differ, one said one carb
should be of "chopped off" variety ie no float chamber. Carb nos
changed (wassell got involved). Run very fast on choke but not
smooth. Wont start without choke. I'm hoping when I strip carbs
I find blocked jets. Am I having fun yet?

What carbs have been fitted - to be honest the best bet to get
good performance are them janpanese fingies!!!
Me, I'd chuck 'em out and go standard, back to the original
singleton! Its a classic bike, it ought to be standard (and
fitted with a roof)!!!!

Twin carb 72 Daytona IS STD!! Stripped them yesterday. Both Jets
clear, needles on wrong setting, too big O ring on one side
trapped/forced in. Putting a flat edge on flange revealed 1/32"
gap in middle on both carbs. Which is bestest Jap carb - Mikuni?
How do I get right carb dimension for Mikuni's? Can I put my
beloved bellmouths on them instead of horrible air filters? So
many questions..
ps Surely running bike without air filters which I have wouldn't
mean it cant start/run without choke?

Mikuni (or however you spell it) are said to be the best!
Yes, removing air filters can upset mixture settings!
I am no judge of Triumphs - best bet for setting up advice is
owners club forums (either Triumph or better still classic car
clubs, 'cos they are warm inside with their heaters)!

These do carb kits, take a pill before you ring for a price but
reading articles from people who have used these kits is all
positive.

All carb gaskets and new needles and flange insulators ordered,
but cant say this will make any difference. I'm told a piece of
glass, emery and elbow grease will flat flanges..mmmmmm..
Anyways, new rear mudguard to order today ;D and I might get
rid of awful dunstall type megas which were fitted as std before
yer ask, and go beloved goldies. Anyone know what size to take
jets up to. Presently .106 pilot and 150 main ::)

Flattening flanges on glass is easy peasy - don't need much
elbow to flatten soft alloy!
No idea about jet sizes!
Typical of vandalistic latter day Bezzer riders to consider
putting the wrong mufflers on an old bike!!!!

They don't muffle much :D and put one on my Tiger Cub in 1964.
It cost £4.50 !! That was more than my £3.17s and 6d wage as an
apprentice.
