Thanks for the help ... That's a clean looking mod. you did there.

Ok, so I left it at 130mm and drilled the motor mount. I also ground off a tiny flat edge on that corner's motor mount washer for additional clearance. That puts the black carb. screw 1mm from the motor mount.

I was looking at the Dubro spinner I'm going to use and noticed it has a lip on it that will close the gap by 2mm (of the 5mm I was over) so that leaves just 3mm which shouldn't be a problem to make-up with the cowl spacing or leave as is.

I also moved the throttle cable wire over 3/4" to put it behind the carb. throttle arm.

There's more info. on this build over at my website:
