This looks like an excellent candidate for 3D printing.

That is great, Glad you found a solution. By chance is that a 22hp carb? I am needing to find one for my CH20. So far $$ is not allowing me to upgrade that 2hp.

Yessir that is a 22hp carb. I'm 99% sure the difference between the 18hp and the 20hp is the throttle stop; adjust the throttle stop to allow the butterfly to fully open and adjust the governor and you have a 20hp. To make it a 22hp, I BELIEVE (98% sure on this one :biggrin2:) you just need to get the main jet from the 22hp carb as everything else is the same. Should be part KH-24-337-02. See that number in the link below. This has been discussed here before and this is my understanding of everything. J-Mech, dvog, or Sam Mac would be a couple good guys to confirm this. If I'm not missing anything, it's an $18 part to get you a couple more ponies. I'm debating doing these "mods" to my 1864 to make it a "2264" this year :biggrin2:

Glad you found what you needed.
Be careful next time....
