I sent an email to http://www.flitelinesolutions.com/ mentioned in post #8 of this thread and they recommended oven heating. I put it in a 300 degree oven for 5 min last night and it easily came free. It is now fully disassembled and ready for cleaning. Also downloaded copies of orig manual from them and discovered that this is actually a 60, not the 74 the owner thought he had. OOPS!! Still will be a good engine when done. Glad I didn't order parts for wrong engine. Looking like all I am going to need in some gaskets and maybe a plug (long) He can live with that, expense wise.

Thanks to all for your sage advise,

Bruce[
