Ive got an 8mm bolt, a long one i had in the bolt draw, one with a good bit of non threaded shaft on it, i cut the head off and cut a slot in it.
Then i lost it and i grabbed a 8mm manifold stud out of the drawer, then i found it again.
Serves two purposes, makes it easier when mounting the engines with the frame tipped on its side. Gives it something to hang and piviot off while you line the bolts up.
Second is it will easily take the weight of the engine when done up in a vice. I usually hang the engine in the vice once its together (usually just the crank and piston in with the starter on) and once you have the coil mounted check the spark. If its no good check the connections and make sure the ignition module is getting a good earth. The rivet can work loose or be a bad connection.
Saves having to put the motor on and off the frame to be able to get a decent spin up.
Not sure how you work it with the drill, on the disc nut thread i would assume, could easily spin it up to check spark.
If its just for a spare you dont need a new decompressor. Just put an old plug in it, will be a bit harder to start.
