Thanks for everyone’s comments and suggestions. I’m going to try a bunch of things. I have other carbs that I can switch out. I do need to get some o rings to stop the unwanted air activity.

xanaphyst I like your air bleed concept. I guess at this point the mechanism is manual? Meaning slide the drill bit in and out. I hope you have success in then making it programmable. I’m trying to avoid the solenoid route. How soon will you be able to test your set up?
