Power valve 4180 HELP PLEASE
Hi all, I’ve been having issues since I replaced the power valve in my carb. I tossed the old one and I don’t think there is way to get it back. Here’s the issue. And it is random! It is flooding with gas on partial throttle under load above 2k rpms. What’s the part number or specific type I need to get the power valve closest to original?
Thanks so much!!

Looks like it takes a two stage power valve which it seems holley stopped making because they decided a single stage would work ok in them. I saw yours took a 7.0 .5 I think they indicated a 5.5 single stage valve to replace it.. Or I think Mikes carb parts has some under #70-46 Might be best to just call Holley and see what they say for sure..
