[QUOTE="cujet, post: 449947, member: 19501"] Tex has a valid point. The CV (constant velocity) carb has a airflow/vacuum controlled slide that regulates and restricts the amount of fuel/air you get. The CV carbs are big enough to make proper HP in the top end, just slow to respond to a whack of the throttle. If you take it apart you will see why, the orifice in the slide is small,,, all the air above the slide (in the diaphram cavity) must go through that hole before it fully opens. This takes time, of course. In the distant past there were kits for CV carbs that helped eliminate the problem of slow response. These kits consisted of a drill bit (to drill out the orifice in the slide) a softer spring (to let the slide raise up easier) and a washer for the needle (to compensate for the higher air flow and lower velocity). These kits often did nothing for top end HP but made the response much better. Chris [/QUOTE]
