Anyway, I called the rest of them common. That they are. Let's look at some examples. But first, I'm going to add one more. I'm adding it a the beginning of the list and I'm giving it the number zero. If any cluster deserves the number I've given it, this one deserves to be given the number zero. It's the most trivial cluster thinkable, in fact it's not really a cluster at all. It's nothing. Some say nothing comes from nothing but this isn't true when you're counting the syllables of the English language so it's worth the mention.

So there you go, fifty common initial consonant clusters (or single consonants or just nothing at all). And there you have half a dozen common monosyllabic words for each of them (without any homonyms). In other words there you have three hundered syllables that exist in English and I've barely even scratched the surface.
Actually /dw/ doesn't seem all that common either the only other syllable that I could think of starting with /dw/ was the /dwin/ of "dwindle".
Anyway, how about some more examples?
51 /sw/ swing, sweat, sweet, swoon, swat
52 /j/ yes, you, year, your, yeast, yeah, yob
53 /pj/ pew, pure
54 /spj/ spew
55 /bj/ beaut, beauty
56 /fj/ few, feud
57 /vj/ view
58 /kj/ cure, cute
59 /skj/ skew
The following may not be initial clusters for everyone. Cockneys tend to drop initial /h/s so 62 and 52 would be the same for them (as would 23 and 00). As for the other six, it is the /j/ which is often dropped especially in North America. In the case /sj/ most of us would drop the /j/ (not just North Americans) a few others might merge the /s/ and the /j/ into /S/ (maybe). Also, for many /tj/ and /dj/ become /tS/and /dZ/ respectively (this turns /stj/ into /stS/).
60 /nj/ new, news, newt
61 /mj/ mute, mule
62 /hj/ human, hew, huge
63 /tj/ tune, tumour
64 /stj/ or /stS/ stew, stupid
65 /dj/ dew, due, duke
67 /sj/ suit, super
Good point about "guava".
The "wh" words don't count for me either but I've included them anyway (number 71) because they count for some people. Not all of these people say [hw]. Some say [W]. I guess if you say [W] for "what", "when", "why", etc., then perhaps the [hw] in "Huang River" is phonemically distinct and would deserve to be added to the list.
94 /hw/ Huang River
I'd included /sj/, /lj/ and /rj/:
14 /s/ soot, soup
67 /sj/ suit, super
37 /l/ loot, loose
69 /lj/ lute, luce
24 /r/ rood, room
70 /rj/ rude, rheum, rule
But I'm not sure whether this is how these words are actually pronounced. Do these Welsh people pronounce them with /sj/s, /lj/s and /rj/s or is the distinction made in the vowel and/or final cluster? The same would go for /thj/, /trj/ and whatever else there might be. I mean, perhaps whilst "through" is still /thru:/, "threw" isn't /thrju:/ but more like /thriw/ and perhaps whilst "brood" is still /bru:d/, "brewed" isn't /brju:d/ but more like /briwd/. I can recall reading something along those lines.
I'm still wondering about your /Kt/ though.
