hello, im new to gas and conversions and i just got a echo 22.8cc i think weedeater that i wish to convert to aircraft use. I got the engine pretty much stripped down but heres the problem, there is a centrifical spelling? clutch on the end of the crank and i have no clue of how to get it off, as well as the flywheel. So far it looks as i will not be able to use the engine as a coversion unless i take the flywheel off as well because the crank is so short. any suggestions? ill try to get pics asap but i cant find the cord for my sis digital cam right now. thanks
