The service manual for my Toro Proline 21 Model 22040 shows the governor should be kicking in at 3000 rpm but my TinyTach shows the mower running at 3300. The govenor linkage seems to be working fine. Should I attempt to fix this or is 3300 okay for this two cycle Suzuki GTS engine?

After further reading of the Service Manual it seems like it has a +- of 150 rpms and you can select one of two holes which would increase or decrease by 150 as well. I will head to the garage and see if I have it in the increase hole which would account for the 300 total.

Since I am not a mechanic despite enjoying tinkering with small engines can someone give me a hint at the easiest way to bump up the RPMs for optimum cutting without putting the engine in jeopardy?
