Partner 7000 won’t start hot.

[ttifin]

I was givin a partner 7000 by my wife’s grandpa and it won’t start back up after I run it for a bit. I just moved to a treed acreage and was givin 5 chainsaws by friends and family. I took apart a Stihl 021 and changed the crank seals and gasket maker and it fired right up runs good. Now I’m interested to get all of them running. Partner sounds awesome when it runs. Any suggestions would be great for me to try. Thanks.
