The raw edge after cutting is a larger diameter hole because of the taper.
I originally thought I would need to weld in the piece I cut off to get it to seal to the carb but instead...
I used a section of black door edge guard on the cut edge to make up the difference.
Fits nice and should seal fine. I kept the original carb to air cleaner gasket in place.
I scribed a line.
Marked the line with tape so I could see it better.
I cut along the line with a rotozip and then used a belt sander to get it flat and level and remove the little jaggies from my less than perfect cut... I expected that so I cut a little less than the final amount I wanted to remove.
You may need to to take some material out of the center bar. I had to to clearance the air horns and the butterfly on my QuickFuel carb.
Final test fit with some plumbers putty. 7/8" at the center, more than an inch everywhere else.
