What I finally found and helped with surging was spring around throttle. I had to tighten spring by seating it in a different spot. That did help. Does that make sense to you ? I would not say it is running completely smooth but it is much better. Still have to do a load test and I like I said before it was fine there.
Also I did adjust governor. With lever off and turning governor shaft it only turned about 1/8"either way. Is that natural ? I thought there would be a hard spot and maybe a nothing spot. Thanks
I'm not sure on that engine about the 1/8 of turn on the gov shaft maybe someone will chime in to your question. Most generally on other small engines about 1/4 of turn of the shaft at least and a definite hard stop at each end of rotation. Usually you do not have to remove the lever when doing a STATIC governor adjust, but the amount of rotation of the Governor shaft should move the throttle from full throttle to idle as the gov shaft is rotated manually when the STATIC adjust is done correctly. You can review how to STATIC gov adjust on-line search.
Theory of manual adjustment is same for most all small engines.
Since a choke did not do any good and your tightening up the governor spring helped you may have a stretched governor spring that is too weak.
