You need to have it work on by someone competent unless you know the circuits and have the tools needed to modify it work
That plugs would make me want to lean out the transition fuel feed circuit only by 30 to 40 percent twocents
To do that you need a good set of numbered drill bits, #1 to #70, a good pin vise to hold the bits and a good set of taps and dies down to #4 size. I use brass #6x32 set screws to modify the carbs to lean those circuits down up
If you don't have those tools or don't want to do the work yourself try contacting Dominic, Thumperdart, on here and have him do it for you scope twocents
