Check the muffler....the spark suppressor screen can get partially plugged on any chainsaw, especially if you have been running the oil mixture a bit more than recommended.
Shaft seals usually make it hard to start from cold or after a prolonged period of storage .
Then it becomes easier to start when you are using it every weekend ( cutting firewood ).

Bert, the condition I am referring is where there is serious damage to the seal. Slight leaking that you imply where the lower chamber can build enough pressure and still idle. My suggestion damage\wear\worse leak is beyond this and thus not enough lower chamber pressure at idle (die) but enough pressure at high to keep running. Using it more frequently won't fix this condition. Just a suggestion to the user's problem.
It was the piston/rings. One ring was seized and piston/head was scored. The seal on one side was very loose on shaft. Replaced head, piston, rings and seals. It runs like a new one...
Thanks to all.
