I have a CD150 Carby with just 128 on the housing where the air filter bolts on and am not sure if it's early XU1 or just another Carby.

128 ?
128A - XU1
128B - XU1

Any ideas?

128 will still be an LC XU1 carb. It may well be the very early sets didn't have the A & B codes?

You are sure there isn't a very very feint A or B stamped on there?

I came accross a set of CD150's a few months ago that a guy was selling and all three were 128. I asked to same question about an A or B and definitely just 128. Same with this one just a straight 128...not real sure, maybe early early version...

mate did this carby have a needle in it if so can you tell me the letter and number on it,,, there is a pretty easy answer to your question, the earlier version 67-68-69 that only had one 150cd carby and they only had 128 stamped on them,, take the full bottom off and turn carby upside down and see what date you have in there. the A and B only came around for the XU1.

Ok the plot thickens, I have a second 128 carb. This is the carby number in this order, air filter inlet, float housing and needle

128A A104 6E
128B A104 6N
128A A104 6E
128. 104 6E
128. Nothing 6E

First 2 pics are the 128 104 6E carb

All needles are 6E with the exception of the 128B carb which is 6N

Ok so what are the dates?

This is the second 128 CD150 with no date..

Ken, this one is 1970 vintage. The 0 inside the circle of dots is the year and the dots represent the months of the year.

Is this one a 128, 128A or 128B?

Dave that one is the straight 128, the picture below it is the inlet housing of that one, 128

The 2 x 128A and the 128B all have just A104, nothing else, no dots...

here is a lesson in the 150cd carby.

sometimes they at the carby body factory forgot to put down the A-OR-B and sometimes they did not put the A OR B next to the 128. it could be somewhere else on the face of the carby

in this pic of the 1970 cast date the dots are a clock from 1 to 12 you will notice that the big number 8 dot as a small tiny dot inside the clock next to it and then the next small tiny dot is number 11 so that carby would suit any lc xu1 built between the 8th and 11th month of 1970

you will also notice in that pic that i put a black mark on this part that a xu1 carby should not have but it will have the small bit at the back of the carby,,,that also means that this carby is no good for a xu1

now to the 6E and 6N NEEDLES someone at some stage has changed the 6E needle out of the 128B carby and replaced it with a 6N needle witch where used on the earlier cars

Gong thanks for the lesson and all makes sense. I have a spare 6E needle so I will fit to the 128B carb and put the 6N in the 128 Carby. I will have a closer look for the A or B on the XU1 carb.

On more question, what does the A104 signify?

Ok need to see if this set of throttle / choke brackets are correct for LC XU1 Carbs 128A 128B 128A.

The bracket in the middle pic is off the 128B and the other 2 are from the 128A

Ok I have another 150CD housing which I have pics of below. This one has A128 stamped on the housing and is identical to the one in my first pic that has just 128 stamped on it. Point to note is both the 128 in pic one and the one below have the same extruded casting knob on the side which confirms both are most probably early XU1 housings.

So the three carbs I have are 128 A128 128 most likely very early LC XU1 Carbs.

Thanks to all that posted.....

I suspect you boys may be waiting for a very long time for John to respond to your requests.

No, just that he seems to be taking a break from the Forum. For how long is anyone's guess.
