How To Adjust The Secondary Speed Screw On Holley

8 thoughts on “ How To Adjust The Secondary Speed Screw On Holley Carbs ” gza06955 February 2, 2020 . I replaced my screw with one from Lowes that I can use a small Allen wrench to adjust so that I don't have to remove the carb to adjust secondary throttle plate opening. An Allen wrench will clear my performer intake whereas a flathead screw driver won't. I believe the size was either 8-32

23/04/2010· (Apparently I forgot to write down what I set the secondary speed screw at because I didn't think it was a big deal...) I keep saying it would be nice to have fuel injection, but I enjoy working on the carb and playing around with it to get the boat to run perfect. Always learn something new from it !!!

Holley 4150 secondary butterfly adjustment Don Terrill’s

16/09/2011· The issue I have is that he told me that he adjusted the secondary opening. I closed it down to just expose the transfer slot the same way I would set the primary. However, now when I set the timing at anything above 14 degrees initial, I cannot lower the primary idle speed screw down any more to lower the idle. The car is right on the edge right now. It idles at about 900 right now and the

14/09/2011· What is the general setting for the secondary opening on a 4150 Holley? I bought one off Craigslist that was pretty new but I think the secondary butterfly opening was messed with. I closed it down to expose the transfer slots like I do with the primaries. But when I set the timing at 14 degrees initial, the idle is already high enough to just about be off the primary idle speed screw. The car
