Hesitation, surging and crap mpg.

[Lawrence]

Turns out that in first/second gear when I gave it some welly it was ok.  In higher gears it ran like a sack of shite.  Was on the way home and planning on taking the carbs out again to check them out (it wasn't getting (enough) fuel to #4, sparking but header was ~50C when the others were ~150C) and 10 minutes before I got home it suddenly cleared and went back to normal.

So to summarise, it still hesitates like before but at least I haven't made it worse
