Holley 4150 Double Pumper carburetors are a perfect upgrade for hot street cars and race vehicles—they're an American icon when it comes to performance. From their roots as the premier carb on many factory muscle cars, to powering thousands of vehicles across the finish line, the Double Pumper is a great choice—whether you're burning up the street or the quarter-mile. The Double Pumper is designed for use on lightweight vehicles with a manual transmission—or an automatic transmission with a high stall and low rear-end gears. These carburetors are available in a gold dichromate or tumble polished shiny finish, along with these features: Dual accelerator pumps for additional fuel under initial acceleration; mechanical secondaries for great performance; dual feed fuel inlets for constant high-volume fuel delivery; and a manual choke for easy control of engine warm up. Order the model with options to suit your application.

So far it’s runs and idles good since recently installed but once under a load feels like it either to rich or lean installed fresh set of plugs and so far instantly fouled out so possibly might need tuning fuel psi is at 6-7 going to install wideband to further see what’s going on.

Yes, Holley expresses that the carb is not ready to run... we mounted it, fed some fuel in the bowls, cranked and it fired up. Of course you will have to adjust everything... when don't you, right?
