Camp Douglas Wi. 40miles nw of wi. dells | Traded 9650/8.1 off for new 9770/9.0 in 2011. On our 11th year with 635F with airbar. We’ve got record bean yields this year along with no freezing of the green stems. Still able to run 3.5-4 mph.
I’m thinking you got issues. I’m sure you’ve already checked/changed air and fuel filters but if not that’s were I’d start.
Edit; yes the 9.0 has more power than 8.1 and it was no pig.
