Identify this Mac engine
I picked this up from the scrap bin of the local small engine shop along with 3 Poulan 46cc and a Homelite 45cc. I am not sure of what it is since there was not much saw left around it. It is about the same size as the Homey and Poulan. It looks like it would be a good conversion. I would like to know the cc on it without having to do the measurements. Any of you guys seen one like it before?
