Float height Rochester monojet

Anyone have the float height measurement for a 250/Rochester monojet? Can’t seem to find it and the rebuild kit didn’t come with instructions

Yup I saw that, it was just so far off what mine was initially set at I wanted to verify. It is also a different measurement than off the chart the gentleman posted above. Not saying you are right or wrong just wanted to get some verification. I appreciate the help.

It depends on the year and displacement.... what year are we talking about here?

Thank you a lot, I’ll reset all the settings. Discovered a vacuum leak where the intake manifold meets the block so looks like I’m doing a new gasket first. Hope that’s the source of my issues.
