Thanks for the get back and the pictures. All I can say is WOW! What you have is what once was a 32cc Poulan/ Weedeater engine. They have been very similar for years with the Poulan perhaps being the better built but heavier of the two. Bigger bearings and crank pin with a real rod but smaller ports than the 31cc Ryobi"s. With all the merging and etc, that has been going on I can't keep up. The new Ryobi's are the old 30cc Homelite and so it goes......Just when I thought I knew it all!......Farley9n
