To get 98% throttle opening my epa is only 56%. It depends on the length of your servo arm etc.


Setting your throttle opening to not open all the way is not a good idea for fuel mileage. Like said above it takes away your carbs ability to be properly tuned across its entire rev range. You end up with a low needle tune.

If you want less throttle opening, use a smaller venturi.
