It's like you're reading my mind!
What scrap pile are you talking about? Where would you find something like that? I have luck on CL once in awhile, but that's it.
When you say that the new engine is lighter, are you concerned about excessive wheelies?
I have an engine just like that from HF that I bought for $70.00, and it's awaiting a project like yours.
Excellent Father / Daughter project.
