Timely post - spend some time this weekend on my recently-acquired AEHS.
As others have noted, the one on eBay
is missing the magneto and maybe other parts. My AEHS is missing much of the governor linkages as well and I plan to fabricate my own.
I can't get a good look at the photos on my phone and can't get to eBay at the moment to say for sure!
The magneto is not impossible to find, I have seen a few around but they are not as common as other magnetos, being pad-mounted and not gear-driven. Keep an eye out and one will turn up.
The shipping cost seems very low to me. This is a large, heavy engine - over 100 lbs - and proper packing only adds more weight and expense. It seems that it should be twice what it is saying.
My AEHS is turning out to be a mixed bag. While it was complete besides the carb / governor linkages, it had a lot of problems:
* The shroud was rusted out on the bottom. I've fixed with fiberglass mat and resin.
* The flange on the carb had one ear busted off. Thankfully, found a replacement that needed rebuilding that I got cheap.
* The air-cleaner tube is cracked in two places. I plan to get some of that MuggWeld alloy to try and solder it back together. We shall see how well that works.
* The magneto was dead as a doornail. I made up a separate post on its issues - basically - the points were so ugly that they needed a good bit of work to get them flat again.
* Starter rope sheave was busted into three pieces. Thankfully, it has a steel center that is threaded for the crankshaft and has a 1" shaft. Took a 1" cast iron pulley, filed grooves for the starter rope, and that works well.
* Confirmed that the oil pump was working, but it doesn't seem to fill the trough up real fast. But, after I ran it, I immediately opened up the crankcase and saw that the level was good and that the dipper was still dipping.
* It is low on compression - the rings seem okay as did the valves, but I need to inspect the valves and rings more closely. I did confirm that the valves are not sticking.
* It does run, and only smokes a little bit when it first starts, so that seems to confirm that the rings are okay but my problem is in the valves.
* It starts hard - I've got to have the throttle at least half-way open and use a little starting fluid to get her to go. And it seems like if I try to idle it, it will die - almost like at low speeds its on the hairy edge of having enough compression to run properly - let it loose enough speed and it just doesn't have the required compression.
