Will the operating engine vacuum keep the choke open?

[juntjoo]

I have the wrong carb that requires a manual switch to operate the choke for my push mower vs the bubble pump action of the mower so I figure I can just rig a makeshift switch but I wonder if it can be one way choke-closed and let vacuum open it. Got me?

The choke is manually operated by linkage on most machines. The vacuum of the engine has nothing to do with it. Get the correct carburetor and quit trying to rig the wrong one. Gees!

Still unwilling to get the correct carburetor for that primer system I see.

It's not that hard
