Re: Holley 4 Barrel, Carb Secondaries Not Opening

I do have idle problems.. I'm fairly new to carbs and can't say that I really know how to properly tune and adjust the idle. I'll have to take it to a mechanic to have it adjusted/tuned.

As for the speedo - Last year the speedo was reading 50 and I got 52 on the GPS - havent taken the GPS out yet this year. I will soon and repost.

also not mentioned here is that there is a small hole on the carb base this hole has a flathead screw it controls the secondaries stop you'll need a small filed down flathead screwdriver i grinded one down put the screwdriver down in the hole turn the screw until the secondaries just seat closed then turn until they just open and you can see daylight this will keep them from sticking closed. this is recommended by holley, the factory seems to miss it during assembly. good luck!!
