The powervalve is't the limiter there are small orifices in the mainbody that are the flow limiters.the large window powervalves flow more than the orifices. I'm running 5.5 pv s and at 250ft above sealevel I'd think 67s or 68s should be close. unless internal things have changed .64s ran great but were lean according to emmisions testing station. Will be watching untill I get my Jets from Summit.I have no chokes and starting takes a few pumps but be careful you don't flood it.May end up buying a pair of off the shelf carbs for colder weather.
