ive made posts about this 79 floozie i found. its made by grycner. it hear it uses a sachs 505 engine. since its been hard for me to find a running 505 for an affordable price ($40-50) i was wondering if i could replace it with another more affordable motor. how would i go about getting that done. i would have to mess with the mounts? is there a motor similar to the sachs 505 that is more common and would fit? let me know..
