it sounds like something has burned out but where do i need to start looking?
Any advice appreciated
On grounds that wisps of smoke can sometimes be decieving, you say it only ticked over for 10 mins. - are you sure the wisp cama form under the cowl?
I'm thinking 10 mins at idle without a good run to warm it up there's a reasonable chance you've just oiled the plugs. Pull them out & see how black they are. (can do this at the same time as Pol's turn test).
Cure for this is clean the plugs then a good few pulls (no choke or you'll flood it more) to flush through the excess fuel / oil & when it starts - make it do some work!
