I'm trying to hunt a carb strip kit ( 10-203 ) before modify rear jets I have extras around... which already looks I found it.

now... if getting bigger rear jets, can I readjust the floaters to set them a little bit lower ? specially being the problem IT LOOKS to be just on rears, so why to keep the 29/32" float adjustments if not needed on regular cruising ? ( so front throttles )

I'm working on save from pinging... I have got success on all small adjustments done. At this moment just getting pinging beating hills on highways with A/C on.

but mileage is getting really bad. I know is logical if you get a richer mixture will get a bad mileage, but the change on mileage has been radical on last adjustments.

Power increase has been also an improve.

trying also to get from 7 ( NGK ) plugs heat range I'm running at this moment when I was searching for the pinging cause, to the more standard 5 heat range
