My brother in law gave me this saw and I'm wondering where to find the model number so I can find parts. I like that it's very lightweight as I mount it on the front forks of my motorcycle to clear trails here up in the mountains ... and my 031AV is just too heavy for that! I'd be much obliged if someone could draw an arrow on one of the pictures to show me where to look! I replace the fuel line and starter rope and it runs but gets hot and dies after a while and I'm also not seeing much if any chain oil consumption so I'm worried about the oiler function. Many thanks from a newbie!
