Please can you offer any advice....

I have a 110 2.5 petrol CSW (58 K miles full service history)
Wilst out today, towing a small trailer, she started to loose any power and
lots of backfire on overrun. When the throttle was opened there was little
or no response then coughing and spluttering and then "SLOW" acceleration.
When slowing down much backfiring again (flames could be seen out of the
exhaust).

Stopped at my destination for 1/2 an hour and She ran well again for 10/15
miles when problems started again. Stopped for fuel after about 30 miles
and all was OK.

Any ideas or sugestions would be gratefully accecpted.

air leaks in the manifold or timing slipped, would be my first guess. Or
fuel starvation.

Carb' icing?

Fuel cap icing up so tank wasn't breathing but the ice cleared when you
removed the cap?

Are you sure that you had not put diesel in the tank.

Otherwise it sounds like it could be a spark, timing, dwell angle
thingy.

Sounds exactly like carb icing. You'll probably find there's no hot air
getting to the carb. I dunno how it works on your vehicle but it might
be missing trunking, seized flap etc.

i had almost similar stuff hapenning when i had a crack in the exhaust
manifold. only started causing troubles once the manifold warmed up, when
crack got a little bigger. then crack started letting air in a caused
backfiring etc, which caused manifold to get even hotter. glowing red hot in
fact.
