does anyone have a smal engine guy that they can recommend? My HS40 engine is complete, but I need to ship it to someone who can get it running. Thanks!

What all did you do to it ? It ran fine when I sent it to you...and I even sent you the video of it running.

The shaft was so badly corroded and there was a lot of lateral play in the crankshaft. I opened it to make sure that the corrosion was just external and that everything inside was good. It was, but the PTO seal is wrong. There is supposed to be a seal with a retainer ring that helps restrict in and out movement of the crankshaft. The points were in rough shape - replaced. I also replaced the condenser.

The entire engine has been cosmetically restored to new condition, but I am now seeing no spark. I'll keep working on it. It will be fine soon enough.

Check your ground wire for a short. It sounds like it's grounding out somewhere

The seal is just a seal, there is a separate C clip, Were those parts NOT there before taking the engine apart (if so YIKES!!!!!)

Exactly...crankshaft end play should have nothing to do with why you can't make it run (unless maybe it was VERY excessive). They ALL have end play even NOS.

Well we know it ran with the old points and condenser so why not put them back in and try it that way just to see ?

I have a guy in Vermont who does beautiful work at a very reasonable price. Has done 3 motors for me. PM me if interested.

Because the points were worked hard with a file and would never be set properly. Besides, they were rusty and this is going to be a show bike. The wires on the coil were so brittle they fell apart. I replaced them and checked the coil. It still works.
