Hey guys! Thought this was the place to post my small carb troubles. So I finally got around to grooving my generator and was pretty sad to realize that it lost fuel economy. My groove didn't look GREAT but I was hoping for at least some improvement. Back to the training manual I went. Ron says that if there's no improvement or loss of economy then there's gotta be a vacuum leak disrupting the wave pattern. I don't know if you can see on my pictures but there's a small hole to the left of the throttle plate. I looked up a diagram for the carb and its a bowl vent. I did break thru into the bowl cavity and built it up with JB. I'm suspecting there may have been a tiny pin hole in the bowl vent passage that I couldn't see. I filled the groove back in with JB to re cut it. My question is...if the bit is cutting thru that vent passage, then wouldn't it be ok to fill that whole passage in and then drill a hole thru the side of the carb to let the bowl vent? I know mikunis are similar where they just have a vent spout sticking out the side. Just curious if this has been an issue for any of you.

First, you need to patch that hole in the throttle plate.
Second, you BETTER seal off the Groove. If there's a hole in the Groove, then the pressure can't build to what it should. Go back to the basics. THIMK. YOU are the Gadgetman in residence. Don't let yourself be drawn into the trap of needing OTHER people to answer your questions if you haven't fully analyzed what's going on, and how what you did affects the processes you're playing with.
Teach yourself to LEARN, Johnathan. It's not your fault.
But it IS your RESPONSIBILITY to fix it.
Go back to the basics and study not just what I demonstrated, but the extensions of that as they relate to your experience.
One thing more. Use the largest bit "Possible" the manual says. You should be using the SMALLEST bit on this diameter of passage.
But don't worry. Reach for understanding first. THEN, reach for help. We got your back.
And you have my phone number.
