here's an [link=http://www.rcuniverse.com/forum/Engine_experts%2C_what_is_it_%3F/m_1531278/tm.htm]old thread[/link] with some pics. it seems that the newer engines have a shorter stroke than mine and are about 22cc. in the pics you can see the clutch housing still bolted to the four nipples/lugs that i'll be using to mount the engine to the firewall. i've seen quite a few of these exact same engines on hedge trimmers of various names, mine was on a "golden-star".
