tuning

Hey, I'm having an issue with a lean mid range that can't be tuned out. It has been there since popping the limiter caps and doing a port match and muffler flow mod (matching the exhaust port outlet and muffler inlet, as well as rounding over an sharp edges and angles within the exhaust port)...

Hi Everyone, Yesterday I got my tac out of the package it’s been in for many months and finally checked my 2 year old G660 that I primarily use for milling. It was almost 90 out and and it was running 12800 rpm. I have not touched the carb since it arrived. I have probably 30-40 tanks...
