I agree with Rick. First time I had my carb bottoms apart was when I did the Freak so I had the carbs out. Brand new, old, it didn't matter what screwdriver I used, two of them would not come out. Stripped the crap out of them. Had to use needle-nose vice grips to crack them loose. Very glad I had the carbs loose. Made it a LOT easier.
Pull your carbs...
