Which ever has the biggest ID. I’m not picky on color.

Ok, I'll check....have to pull black one and check if we cut lo speed needle, too....was an afterthought.
Give me a bit....I'm hungry now!

 

[Buckshot]

No worries. Don’t want to step on toes.
AND I can trim low speed needles with ease.

Tim, the snout on the vac carb may be oversized and require machining down, My Zoom vac needed it.

Is Speedmaster not making the aftermarket cards anymore?

No, from what I was told....it's indefinite, don't want to get into details here...that would be up to Harry @ Speedmaster.

Buckshot, both VAC and Beta EVO carbs come in at .354" bore....now, here's the caveat - the boss on the VAC carb is just a smidge deeper into the rotor housing, but could be milled/lapped down....we're talking .013"....also, the OD of said boss is a bit more by .039"....carb bodies and bolt pattern are identical.
From my perspective, it's a simple adjustment on a lathe, or open up rotor housing interface a bit....chamfer on boss not out of the question, either.
Your call.

Hi John, yeah, but very easily doable....if by 'snout', we're talking about rotor housing interface boss. Other than that, bodies are virtually identical.
A lathe could very easily cut a chamfer on the OD, or simply cut the OD of boss down. The differential is ~.039"
Thanks!
