I overhauled the engine out of my '79 this winter. Cases split, all new gaskets, seals and crush washers, hone and re-ring, valve job, new clutch, sonic-cleaned the carbs and put a full kit in them.
The engine got torn down in the garage but the weather got too cold and my garage heating project is on the back burner (arrrrrr...humor) for the foreseeable future, so everything got carted into the basement for repair and reassembly.
It went down in pieces, it's ready to come back up fully assembled less carbs and alternator cover.
I don't have access to a able-bodied second set of hands, and I'm too old (smart?) to lug that thing out of the basement and back out to the garage by myself.
After mentally considering various alternatives, I came up with this:
A bracket that bolts to the two rear engine mounts and sits as close to the cases as possible.
The bracket is bolted to the bare engine after it's taken off the engine stand.
The engine is set on the shoe of my hand truck and the ears on the back of the bracket are clamped around the vertical brace of the handtruck.
A tie-down strap is cinched to the top motor mount and the top handle of the hand truck to keep things stable.
It'll still be a job to lug that thing up over the basement steps, but it's a LOT better than complete brute force and ignorance. I got the ignorance covered, but @ 64, the brute force ain't what it once was...
