i am in the middle of testing the if this setup works better or not. here what i have. testing on a ported 61x/61x.std bore cylinder. 200 psi compression,b-pipe. msd cdi, boat was running with a set of sre 46 on it. i had my 46 blackjacked . so far it runs pretty good still have to work on jetting some. (got a flat spot in the middle) but if i gave you the ski to ride you would think theres a set of carbs on it not one. i have another stock wet-jet kraze that i am going to put on the ski to see how much better the blackjacked 46 is. all and all i say go for it. (nothing runs as good as a set of dule carbs)
