That hesitation with the 42 pilot LTR needle#2 178 main is caused by being too lean on the needle straight section diameter. Going to a #8 slide will only make it worse. Go back to the #3 clip with the 42 pilot and 175 main and it will work better. Even in the #3 clip the LTR needle is border line lean at off idle at sea level 70 degrees so don't run the air screw out too far. Other options are CCK#3 for a very smooth power band or a N3EG#3 with a 175 main for a stronger mid to top pull. These are sea level settings at 70 degrees F. oil mixed at 40:1 pump gas 91 octane. If you want really clean and crisp jetting, you need to have the cylinder head cut to reduce the squish and get a cleaner burn. Otherwise the jetting will always be a little dirty in hot weather no matter how you jet it. Dave
