Not sure this is worthy of a tech article, but the forum has been so helpful over the years here is a small attempt to pay it forward with a longstanding problem I have now solved - perhaps I am late to the party...
I drive my carbureted bronco on weekends. With today's modern fuels I find the carb bowl is typically dry and it takes 20 seconds or more of cranking to get the carb primed and start the engine. I got into the routine of popping the hood and spraying a little starting fluid in there to skip the long cranking process. But I am lazy, and wanted to put an end to the routine of opening the hood and removing the air cleaner to spray starting fluid or gas. I just wanted it to start right away. I have run Edelbrock, Holley, Street Demon and all had the same issue. I now run a Quadrajet and it is hands down the best performer for me - just tired of the hard cold starting problem that all carburetors have including the q-jet. I run a mechanical fuel pump for the reliability and silent operation compared to a noisy fender mounted electric pump (Holley red pump) I ran in the past.
In talking to my latest superhero Bruce at https://www.carburetorsunlimited.com/ he let me onto a trick he used with his son's Jeep. I took a few minutes to draw it up below and basically is it a small quiet $50 frame mounted pump that is only activated with the start circuit. The design of the Precision E16010 pump allows for the fuel to prime when activated by the starter circuit but pass through fuel after it has stopped running and the mechanical pump is carrying the load. The cold crank now takes just a few seconds and I kept the rest of the setup as is. Hope this helps anyone looking to maintain the mechanical pump setup but fighting this cold start problem along the way.
