It's time to rebuild the carb. I was hoping to make it thru the season.

It is a Holley 4160 in a 1986 MC with the 351. The original owner had it rebuilt in 1998. He gave me the box with the old parts and his notes about the rebuild. It looks like it came with a 2.5 power valve, it currently has a 6.5.

The renew kit from skidim comes with a 2.5, Summits kit comes with the 6.5. Which power valve are you guys running?

The 2.5 is the correct marine power valve.
