I am a little old guy @ 67, 5' 7" and 145 lbs. Have pulled this engine a few times over the 25 years I have owned her, most recently a few years ago. Have often thought about building a frame like you did but always ended up manhandling her. If you remove the oil filter, she will slide forward so you can get a better lifting angle. Then grimace and throw her up on your work bench. Having said all of that, if there is a next time, I will build a frame! Bet 2x4's would have been plenty strong enough.
