I used a tire depth guage to measure, it only has 32nd and ml so I used 18.5 ml to get close to the 0.725 inches. Difficult to measure. Seems my original was around 15 ml. I find it hard to believe it was that far off. You tube says measure with carb at 30 degree angle, I saw none of that in service manual. Is something amiss?
yes you are correct, old cv carbs are the round not square like newer ones and the float adjustment is different the setting for round style is .690-.730

Appreciate the replies and the confirmation I am going about it correct. I'm unsure how accurate I was on measure, so will confirm my setting by using the drain tube method as per previous reply.

I have the same carb with round style floats, they are great carbs adjusted and jetted correctly, float set higher will be richer, lower leaner
