Hi Byomarimba
My mistake, I was in a rush when I sent the reply and always get confused when I rush responses.
I have found the spitting back through the carby is caused by the speed screws being grossly out and the metering lever is set too high.
I would try richening up the low speed jet slightly to improve starting. Mine was sensitive until I got it in just the right position.
My favourite chainsaw isn't actually a tranditional chainsaw at all - its a ryobi expand it pole pruner attachment. Got it from bunnings on a stock clearance model for $40 from memory (store closing). With a few extension poles, I can get most things cut with it.
Though I suggest wearing a hard hat - I managed to spear myself in the head with a wayward branch
The little 12 or 10in 25cc arborist saws are good too
