New Holley 4 bbl

[Mbrown]

Just purchased a 87 Minnie that the previous owner had a New Holley 4 bbl recently put on, went to get the rig smogged and the tech said it was running too rich and it didn't pass. When he did the High rev test the right side exaust from the manifold turned RED HOT. The tech said it was running rich down low but lean at higher rev's and the gas wasn't burning causing the red hot exhaust.
The tech is going to adjust the mixture to hopefully solve this ..
Is he correct is my question...
Many Thanks in Advance !

Holley has a catalog of replacement carburetors. You can look up 1987 Ford Van with 460 V8 and there'll be an order number. Also, buried in notes and details, will be "not for RV use." I think they realize the load an RV represents and understand their generic carbs are not designed to accommodate it.

Double check the number is the correct oem replacement.

Wow, that certainly wasn't the new I was hoping for..
Welcome to Rv ownership...I guess ¿

Probably not.
It sounds like it needs re-jetting which is a daunting process for the person not accustomed to doing it and a time consuming one for those that are experienced.
If just adjusting the A/F screws wont fix the one you have, you might consider getting a rebuilt replacement carb for your exact application.
