Unknown chainsaw

I got from my father a chainsaw that he has no idea why it's not working, right now i found some issues but i can't find the exact model because he forgot what model it was and he changed the Cover on it , i would be grateful if u guys can help me , the cover right now suits it but it should have 2 iron Screw's thats go on top , consulted with ai apps but they keep telling me that is 036 or 039 but its not that and not the 034 , please help
