20 vanguard carb and intake on an 18

[18vanguardFL]

What all is needed to be done when putting a 20hp carb and intake on an 18hp vanguard?
Can I still use my stock air cleaner? What about throttle linkage?

Any help or tips, especially pictures! are greatly appreciated.

And yes, first post, y'all have the most know how on small blocks I have seen anywhere!

Need engine model numbers to look them and see the iPls. Most theses days hp is gotten thur the carbs like a 18hp-27hp the most hp is gotten thur the carbs most of blocks,pistons, ect are the same and some can be interchangeable to the other.

Most do not bother using the governor.. linkage, air cleaner etc will not fit from the 18hp
