[Mgs] Miss / stumble

[Paul Hunt]

It stumbles at cruise i.e. a steady throttle?  Sounds like generally weak 
mixture then, that the accelerator pump is compensating for in a large 
throttle movement.  Did it do it before?  If not then look very closely at 
what you did.  If you can reproduce it by holding the throttle open at a 
standstill clip a timing light to each plug lead in turn and see if there is 
any sign of erratic flashing.  Could be a dicky plug, or a lead for that 
matter, I'd swap them back one at a time and see what happens.
