Great info. I like the idea of going thru the bottom of the metering block. I will give it a shot. I could probably just change the metering block, but modifying the original will be much more fun
i was looking on line sometime back and found some aluminum plugs for carb holes, believe it was Mikes Carbs, if you don't want to do the set screws. set screws will need to be sealed. I've found that playing with the air bleeds can help some but in the end it's fuel volume you need and the only way to increase it is bigger idle jets. I really go after idle jets anymore for lower rpm.
