Not digging up the Instructions but I believe it states that if you take the carb and turn it upside down, the float level is 3/4" when measured. Can't remember where the measurement is taken (too early in the morning)
BUT if you are going to do it the Shop way, then you need to have an adapter that attaches to the Carb Bowel and runs a clear tube up the side to visually see where the level is when mounted on the Manifold.
If no one chimes in soon, then I'll look it up later today.
Actually the Instructions should be posted here somewhere as a CAT 22 runs a K5 also.
