Hello, this is my first post and looking for advice from you fine people.I removed idle stabilizer from my blackmax 135 0c261170 and have lost 5 knots in speed I did not adjust timing,is this normal or should I revisit the carb work I just done,cleaned them with new gaskets. I also did heads and manifold gaskets.checked spark and comp is 123 to 125 on all 6 I am cautious to use boat if it is a lean carb, thankyou
