I know most here dont run carbs,

But I figured somebody might know someone, somewhere who does.

I have a holley converted to E85 and im having fueling issues. at WOT im leaning out real bad.... no matter how much I jet im not seeing any change in AFR. I am pretty sure I have tracked my problem down to my carb boosters... there too small at .110 which is standard gas size I believe. I want to try opening them up or replacing them with .160 or .170 sized pins and see if that improves my top end AFR.

I currently have both of my power valves plugged to avoid boost enrichment until i get the main metering circuit straightend out.

my tune,
hsab- .070
iab- .025
pmj- 81
smj- 91
primary and secondary powervalve- plugged
squirters- .032
needle and seats- .130
factory holley blocks
50 cc acceletator pumps

question is............... how do I change the boosters? I see a tool to do it...... for F'n 300 bucks! rediculous....... does anybody know someone or how to do it at home on the cheap?
