Hi!

Your engine is a Poulan built Weed Eater, Sears branded, and they are less than popular for conversions of any type. ( with the possible exception being a blender) There is a larger version of the engine, 32cc, which is only slightly more popular. They are well made and do a good job with there intended function. Apart they look very similar to the Ryobi but are heavier and have smaller ports and a dinky carb. I hope this helps......Bob
