Well, employing a considerable amount of guesswork but finding the answers that fit, I am quite pleased to say that I have only two incomplete answers left.
These are4 down and 9 across.
4 down is: Lout pursuing goal ultimately to idly hang around (4)
First letter L and I'm fairly certain the answer is LOLL.
9 across is: Fuel broken-down Chelsea tractir disgruntled setter leaves (

Letters: C - A - C - L -
As far as I can see, the only word that fits in is CHANCILY, but I've no idea why. Anyway, I have now taken a look at Big Dave's blog and quote as follows:
These types of clues, known in the trade as composite anagrams, are not very often seen in these sorts of puzzles as they have specific rules,
Basically, it works out like this:
The answer = an anagram of a word or phrase minus a word (or an anagram of the word).
So, take today’s clue and remove SETTER from CHELSEA TRACTOR. There has to be an anagram indicator with setter as the letters are not in order. Them’s the rules!
So no wonder!!
And finally, could you please remind me why the answer to this clue is STUBBORN? Or tell me why it is wrong!
29 across is; Hard to work reaped field the French cut or glean finally (

Letters: - t - b - o - n
Thank you.
