Hello all. John W are you out there.
This guy from the UK has a video on youtube with the same engines i
have, Does any one know him or how to get in touch with him, I just
Emailed him and maybe he will respond.
http://www.youtube.com/watch?v=GY0cjQvCJ4c&feature=related
If any one living down that way that mite help me to get in touch
with him would be greatly appreciated. I have been looking for a week
on the internet and theres nothing on these engines. wiring and fuel
and oil pluming systems. Im all most ready to take them back to the
scrap yard were i got them.
David
