Re: My new project 86 Silverado
Got a performance rebuild on my Quadrajet... built by Lars Grimsrud
Here are his notes on my carb...
"The carb checked out really well after a few setup modifications and after all the plugged fuel and air passages were chased down... I ran it through all modes of operation from cold-start, hot re-start, idle, and no-load cruise. I also tested for secondary operations and WOT transition. Idle is glass smooth, off-idle response is crisp, and mixtures are right where they should be - see photos attached of your carb running on the test engine with actual air/fuel ratio and idle rpm. I have the A/F set at 14.2:1, which is perfect for today's pump gas, and rpm is at 850 so it will idle with your cam. I have removed the rear pulloff (these are no longer available, and they were not used on the performance application carbs), and I have installed and tested the electric choke per your request - the choke operates perfectly, and was tested on the engine (note the choke wire hooked up in the photo)."
Here's a few pics...
