Help with a banjo cooker

[maltster450]

so i was brewing up a big scotch ale last night,
i loaded my boil kettle with too much wort, and as i looked away for a moment, i heard sizzling, turned back to see my wort boiling over,
once i got that taken care of i noticed that some of the ports on my burner weren't lighting back up
look a look at it in the light of the day after the thing had cooled,
all covered in burnt sugars
is there anything i can do help this?
i hit it with a wire brush, and while it did get most of the heavy stuff off it still isn't lighting back up right
what can i do?

Can you pull off the head and soak it? Don't yet have a propane setup myself, but that would be my thought.

wel its kinda all one piece, so that is hard, the real trouble is that i don't have anything big enough to put the thing it to soak it in vinegar. on the up side after snooping around a little i've managed to get a lot of power back by finding a drill bit that fit and lightly running it through the stuck jets by hand,
