I've just bought my first HD, its an 1974 XLCH and i'm starting to build it.
I'm not sure what type of carb I have on it, your help will be much appreciated
Thanks,
Gilad.

bird in hand so give it a try. the sportsterpedia is a good sorce of info.
hands down the most popular carb for the iron was mikuni vm38 round slide carb. i run one on my 74ch since 1975 and over 175k miles. they are easy to tune and perform well. they are simple and have the best start circuit i have seen and no accel pump for young kids to twist on and flood the engine. i also run the compu-fire ignition with the mechanical advancer. the ultima ignition is a good upgrade and with the timing cup and electronic adv control. i had p cam and 9:1 setup but now run 10:1 and y cams.

It looks a much later carb than your bike, which suggests it is worth keeping IMHO. It's H-D part number is on that red label: #27502-86B. The 'B' simply means that it is an upgraded carb relative to when it was originally introduced, which is 1986, as indicated by the -86. If you post that number into a search engine you should see confirmation that it is a stock 1100cc Sportster carb. By coincidence the 1100 was introduced in 1986.
It is unlikely you will be able to get any genuine Harley spares for that carb, but you should find parts, such as a rebuild kit, in the aftermarket.
