Want to try? Only too willing (4,1,4)
I believe the answer is:
like a shot
'only too willing' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'want to try?' is the wordplay.
I cannot quite see how this works, but
'want' could be 'like' (liking is a kind of wanting) and 'like' is present in the answer.
'try?' could be 'shot' (both can mean an attempt) and 'shot' is found within the answer.
A single letter 'a' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for like a shot that I've seen before include "Bally" , "'Pronto!'" , "Fancy a drop to drink" , "What serious drinkers do" , "Enjoy field sports" .)
