Conner299: Looking good, my hearing isn't the best but your video sounds like a "valve clack" to me.

This pic is mainly here to show the two spark plugs. You can tell which one the PO had in it. He had to have two washers on the outside, just to get it to seat right. He was a pretty cool guy, so I've been keeping him updated on the progress. I had to rib him a little bit, for that one. I also had to replace the sediment bowl. I'll be damned if it didn't start leaking, from the shutoff screw, a day after I got it home. Not even going to tell you guys how many wraps of Teflon I had to out on it, just to get it tight and oriented correctly.

Yeah... Ive heard that as well. I adjusted them correctly, though. The "T" on the flywheel was centered in the view hole. After they were adjusted, I turned the motor over till the "T" was visible again, and double checked to make sure. Would they still be able to clack, and what would cause that?

Well... Now that I have her at my house, and not the father in law's, I did some more investigating. Definitely not the teaser. I was able to watch her run, without the clutch cover. I'll dig back into the valves, and triple check my clearances. I did get a last cut in, for the winter, though. She definitely needs clutch work. A little grabby, coming into gear. She does cut a nice stripe, though.

Conner: On a motor I had, the valve seat insert came loose and made a racket like a out of adjustment valve. It drove us nuts until we finally figured it out. I'm sure you already checked, but in case you haven't, warm the motor up and then give it a quick look. And believe it or not, the motor ran pretty good with it in that condition.

OK... So my internal mechanics newbishness is showing, and I need to tuck that shizz in. I needed to adjust the valves, and just assumed that any TDC was the place to do it. Well, I think I did it on the exhaust stroke, and I'm guessing it needs to be done on the compression stroke. I just figured it would be the same on either stroke. Correct? The pics show the valves on TDC("T" lined up in the view hole) of exhaust and compression stroke. The pic with the large gaps is compression, and small gaps are exhaust stroke. Now, here's another thought... Do I adjust the exhaust valve on the exhaust stroke, and the intake valve on the compression stroke? I'm assuming the exhaust stroke has little resistance while turning the front pulley, and the compression stroke has a fair amount of resistance while turning the pulley. I'm off to dig in my service manual while patiently waiting for a reply from the gurus. Pics will have to wait. Phone is being goofy. Hopefully you guys get the gist.

Edit: This is the pic with valves adjusted on the exhaust stroke.

Well... I figured it out. I goofed up. I had adjusted my valves on the exhaust stroke. I feel like an idiot. Needless to say it runs much better, and sounds better, also. I took a video, but Im not going to put it up. Theres still some noise, and it sounds similar to my valve issues. That, I do know, is from the clutch at least.
