Your idle should be set: Curb or slow idle 550 - 650 rpm. Fast idle 1000 RPM. If you are using a dash tach take that with a grain of salt. They tend to be very in-acurate on these older units. Allowing that you have "Greyhound" ratios 2350 rpm should give you 72 to 75 miles per hour, charter, GM, or economy gears (all the same) will produce nearly 90 miles per hour @ 2350. Pretty scary as the tires on your unit are rated for 65 miles per hour max. Setting the idle speed should be done with a highly accurate meter. As the govenor controls both idle and high speed. Get both set. I recomend 2250 on the high speed, This will give good highway speed and good engine life. 2350 used to produce speeding tickets when I was a driver. Good Luck |
