[MV] M-43 troubles

this past weekend i took the advice from the list and insulated my fuel
lines to prevent vaporlock
and golly would'nt you know it but i think it worked. maybe it was just
me being too hopeful but i'm sure
it was easier to start after a run in the hot sun. two other things i
did was a compression test and set
the timing.the compression test gave me 90 psi on all cylinders so i
figure thats fine. i got the timing light
going with the clamp on a car plug cable but i had a hard time getting a
good marker reading. it was
jumping back and forth under the light so i set it as close as i could
to the pointer. my timing light does'nt
have an adjustable dial on it.do i need that to get an accurate reading?
this is all a vain attempt to restore
the engine to full power.i get a good idle but as soon as i rev high it
coughs and sputters and backfires.
i've got new plugs,new points,condensor,good batteries,rebuilt carb,new
regulator,a steady fuel flow after
the fuel filter,air filter ok,fuel cap off, idle screw set,but still i
get weak accelerator response. next i'll test the
coil but then i'm out of ideas. the plugs have a slight black sooty
deposit but nothing like the caked on soot
photos you'll see in manuals so i'm thinking their ok. i'm scratching
my head. any thoughts?
