If the mains are stupidly big but the slows are fine it'll tick over ok, but go daft rich at more than mid throttle.

Does it rev past 5 without load?

well just gone through both sets of carbs checking for any differences
and looks like i got mc21 carbs fitted Carburettor Type TA22
both sets look identical has 128s mains 38s slows i guess the s stands for se/sp maybe
can i still use these carbs or am i best off with the oringinal set that have seen better days
