I had two chain saws powered by O&R engines..shoulda kept them,but they both refused to run well and carb parts were very hard to find after the late 70's when my dad got them given to him,so they sat around "forever" and eventually got scrapped when I junked an old truck bed full of iron I'd collected over the years--I could have used the bars and chains off them on some other saws,that you cant seem to buy anymore,for 1/4" pitch chain..
I had a "Tiger" generator years ago too,but only got it to run for about 15 minutes before it seized itself up solid...had plenty of oil in the fuel,I think it was run on straight gas before I found it though..
One of my small engine service manuals shows "Advanced Engine Products" as being the makers of O&R engines..no adress or other info posted about them,unfortunately..
