I have replaced that stud on a BCS tractor. The original was stripped out and the repair required rethreading to fit to a larger stud. I bought the larger stud from Earthtools.

Is that counter-rotating tiller you are using?
Is it better than regular one, how is the Grillo behaving with it? One more question, have you managed to change the bolt mentioned before, what happened to it in the first place?
It's the counter-rotating tiller but i inverse the rotation.The counter rotating tiller it's good only on hard terrain or teren that have not ben plought.On land that is plowed is good normal tiller.
I have a 11 month old grillo g 110 with gx 390 and i check valve clearence and they had to be adjusted.It's ok for that engine to be adjusted after aprox 70 hours of work?
According to the original Honda Owner’s Manual, the valve clearance should be checked - and if necessary adjusted - every 300 hours. Based on that, it doesn’t sound right that your valves were out of adjustment after only 70 hours
This summer I passed 300 hours on my GX390, so I checked the valves for the first time. The intake valve was bang-on, whereas the exhaust valve had a clearance of 0.35 mm, or almost double the recommended 0.20 mm! Due to the excess clearance, the de-compression system hadn’t worked properly for the last perhaps 50 hours or so. In the future, I will check the valves more often.
