weber tuning/breaking up when floored??

[whit]

Do you have good weber skills.Ive tried everything and still getting breakup/stutter?Have to keep it floored sometimes to keep it running and it stutters and wont go above 4000 rpm or so.

Ran it at 3-6psi. carbs and lines cleaned.

Bit difficult to tune webers,,,,the 2 mixture screws turn em in lil by lil until engine try to shut off then back up until idle goes up stop when it does do this to both screws on both carbs,,then comes the tricky part you have to adjust the screw in the middle linkage to make both carbs work together , as you adjust it the sound will change on the carbs,loosen the spark plug cable on plug 1 and 4 as you adjust you can lift the cable one at a time and see if the engine misses more on #1 than #4 or viseversa adjust that crew on the middle linkage lil by lil until you get em to work together then you have to move the timing a bit tooth advance it ,, hope this helps,,if not try you tube

The idle screw adj. worked well.
