Farmer Bill 70

I was just reading a post from someone tuning a JD60 for slow races but can't find it now. I have a JD 70 that is used on a 61 ft. PTO auger at harvest & taken on July 1st each year to the slow races in our small town. My manifolds had blown apart like so many others so I built my own twin stacks & blanked off the exhaust passage on the intake.
It has always run real well at low RPM if carb. is tweaked just right ! Presently sitting in the shop it will run all day at 92 to 96 RPM & never miss a beat. Now I have to figure out something for stacks -- At present the pipes stop just at the corner of the hood & it's a bit LOUD------
