Chainsaw Repair

Thanks for the reply. Im not realy sure exactly whats wrong. It takes about 12 pulls to start and doesnt seem to have much power. Im cutting cord wood nothing realy more than 12 inch and it powers out real easy. I would like to go with the 44.7 rather than the 44 would that make a noticable power difference? Im a green horn it will be the first time tearing into a saw. The main thing is I dont want to buy low quailty parts which one would you recomend
