Who knows the easiest way to install the engine in to the frame ?
Answer - There is NO easy way!
However - There is a way by which one person can have the engine bolted into the frame in easily less than 30 minutes - by themselves ! This tactic may be no secret to anyone - but i doubt it.
The EASY way is to slip the bare frame OVER the engine. To prepare, protect the frame from scratches, however you desire. (I use 2 layers of paper towels, wrapped in duct tape.)
This procedure is VERY EASY when using two people. One person can hold the engine from moving. (Still best to block engine into position, even with two people.) I use wooden blocks of different sizes with terry cloth shop towels laid over the blocks.
Procedure as follows:
1. Lay a thick, yet firm, pad on a solid surface. (I use 2 folded towels & lay them on the concrete floor.)
2. Block up engine so it rests on it's RH side (on points cover) on soft pad, perpendicular to solid surface (best to use an old points cover).
3. Carefuly slip the frame over the engine & when all lugs are aligned, drop in the rear lower through bolt. Next, drop in the front lower through bolt. Last, drop in the top through bolt.
4. Carefully bring the engine/frame assembly to the upright position.
