holley 4160 help
Hello, proud new owner of a 87 ps190 indmar351 vd1:1. I recently rebuilt the carb, a 4160 list 50419-1, assuming it would fix the no idle condition. The boat idles great now, but runs rich as heck up and down. Could this be a power valve issue (put in a 2 in/hg), or something else? Any insight from a carb expert would be great. Thanks!
