I did two washers on the needle, 1.75 turns out on mixture screw and it runs great. Flat land speedo shows 65 maxed out no more sputtering or surging.

You may like to check out my eBay store for the "first tune kit" this will help you tune the carb and has other good fist set up parts too.
The other is the valve adj set with metric gauges and the special spanner.
Also I suggest the "Go no Go" method

Yeah it's .038mm my bad... I'm not buying some special kit on the slow boat from China when I need to do them now.

I would suggest setting them to .05mm or .002in. Any smaller than that is considered out of spec on these motors.

All of that without a sales pitch too. Amazing.

Don't listen to them, they're all wrong. Hahaha!

A good rule of thumb for any small motor is .003" intake and .004" on the exhaust. It's a safe bet and will perform well. I might take mine a little tighter, maybe .002" and .003" now that it's broke in just to try and squeeze every bit of performance out of it. But I also know what "slight drag" on the feeler gauge is, some dont.

Damn, I forgot to include my sales pitch..

Want to be obsessive compulsive with lash? I can zero my Mituboyo 0 -.030" dial indicator using my clamp base and literally measure the back lash of the adjuster. It measures in .0006" increments. It would be a lot of work, but a lot harder to screw up lol.

Buy one now!
