There is no such a thing, called idle jets on a Holley.
Hmmmm then what would cause it to run so rich at idle? Have to replace the metering plates?
These are the specs on the carb. Had the idle screws all the way in and it was to rich.
You have a bad power valve.. I suggest you invest in one of these books and study up on how a Holley works, you can't tune em if you don't know how they work..
I understand Holley I'm just not familiar with them. And how did I get a bad power valve out of the box? It's a brand new carb and hasn't back fired at all
Well, you asked about idle jets I figured you need to learn about them, lol, Maybe the PV is loose??, if it's a new carb need to make sure everything is tight, and make sure it's all what it's supposed to be, you could even have the wrong one in there who knows, wouldn't be the first time that happened, lol, but if it still runs when the mixture screws are all the way in there is an internal leak and PV is the first thing to check, of course if the bowls are loose you could have a leak elsewhere too..
Ya I understand Holley aren't my best. Qjet and Weber and edelbrock I'm pretty good at. I'll check all that thanks. Haven't opened up a Holley in a while so I'm having some brain farts.
POW! I have had a similar book by them that was published 30+ years ago. It's my bible on Holleys. @541joseph , you need to study one of these books, if you want to truly understand how they work, and how tuneable they are. Your new power valve doesnt even have to be bad- it could be the wrong one, for whatever vacuum you have at idle. I spent 20 bucks on one back then, and I still won't loan it out to anyone. Gold there....
Maybe IDAs and DCOEs could be better then a Holley but not the rest Slobberjet and Edelturd no way.
I will look at one when funds allow!
Umm. I didn't say this, or anything.....
ive never had an issue with qjet. Good reliable carbs.
I'll look for a book when funds allow
I’m not a fan and most on here will tell you that lol I am gonna do a how to tune video on an Edelturd though, once I get my paws on one.
