Wayne, my manual says only to keep it below maximum RPM for the first 50 hours. Maximum for you is 2600RPM or 2700 for me. I have been pretty consistent at 1900 to 2200 RPM. Rat...
Thanks for pointing that out RaT. It's still very interesting to think about what could be done with the 3830 engine, however, it will be a long time before I even think about modifying a 30 series. I'm still getting used to the 2 cyl Shibaura (Sheboom!) in the Ford. What a contrast to that smooth L4330 - it sounds nearly as quiet as a gas pickup engine, even when running the bush hog at PTO speed.
