g'day terry,

yep i go with peter to some degree check the fuel for cleanlinest
could contain water from build up especially if you top up the can and
don't make sure it is clean and dry before putting in new fuel. i
would also suggest by the sounds of it that it needs a new diaphram
fitted into the carby, a little expertise is needed here so don't know
if i can talk you through it might be best to let the professionals do
it!! of course if you live next door i'll do it for a XXXX.
