How to get your Carbureted Engine to start faster.

I used to hate it when my engine would crank and crank and crank, and finally start. You can fix that! Let's talk about How to get your Carbureted Engine to start faster. You can do two different things. One, install an electric fuel pump to prime the bowls and/or add a check valve. If I can do this at home, so can you!

Badass car! I run the stock mechanical fuel pump on the 460 in my 74 f100, putting a check valve between the pump and carb has to be one of the absolute best mods under 10 dollars I've ever done. I also have a clear filter between the check valve and the carb so I can see what's going on. She fires off faster than fuel injection even after sitting for several weeks. Once warmed up, you barely have enough time to twist the key before it starts.

In addtion to everything seen here with a carbureted setup, a great thing to add would be a +12v 30a relay and fuse with an adjustable seconds timer built in, so no more using a manually operated switch to turn the electric pump on and off, convinient since you might forget to turn the manually operated switch off while driving. With the circuit properly hooked up, turn the ignition key on(no start), the relay will activate the electric pump for 3-5 seconds, then automatically turns the pump off, the timer resets itself after all power is removed, like key off, that should provide just enough time to fill the fuel bowls for quicker starts, hot or cold. Much like what the ECM does for EFI cars, when you turn the key on, the pump is primed for a few seconds, then turns off, of course the ECM waits for an RPM signal or oil pressure to turn the electric pump back on to run the engine for saftely reasons, same principle here.

If you don’t have an electric fuel pump as I do in my 70 Z/28 and you want an instant start, you can add fuel down the vent tube to get fuel into the bowl if you drive your car something like once/wk.

I smiled when he broke out the engineering paper

@harryreeves5575

Aren't you still pumping fuel through mechanical fuel pump when priming carburetor . It would be less work on eclectic fuel pump to by pass mechanical fuel pump when priming. You by passed electric pump but not mechanical pump when priming 😮😮😮

i can let my rig set for a month no problems never had problem even after 3 months of sitting it fires right up running a 450 hp 454 crate engine then put an intake and 850 on it that really made it come alive

Man I’ve looked at a lot of videos about fuel vapor vapor lock everything you go to the south 83 F150 control valve never heard of it I’m glad I met you

I would think that you could turn the pump off as soon as the engine starts, as the bowls are full.

A simpler system is using a "Facet" fuel pump 4-5 psi. It's a flow through bypass when off (not pumping). The body is grounded to chassis with only one wire to a momentary switch, then routed to switched keyed sourced fuse. Once the carburetor is primed the fuel pump takes over not starving the motor of fuel. This would eliminate check valves, tees, and additional fuel hoses. Great alternative, well executed video.. cherry ride!!

For three years, I have been plagued with an intermittent engine that would die under heavy fuel demands. Now I know why, and can’t thank you enough! When my electric fuel pump was off, the fuel pump on my 1948 Lincoln V12 could not suck enough fuel through my Carter fuel pump. FINALLY with the bypass/check-valve installed, my issue is over!

Very Nice Job On Video,Didn’t Think Of The Check Valve Idea , I Always Did The Pump And Crank Method , Till It Started Deal On The Old Tin Indians ,Thank You !!!

Nice video and had some great ideas. I have a 1984 Honda CRX (totally different vehicle but same basic concept) that runs beautifully, except since it has a carburetor and mechanical fiel pump, it takes a lot of cranking to get it going when it's been sitting. I had thought that it was due to the evaporation of the Ethanol blend fuel and did not realize that it could also be due to fuel running back to the tank.

I wired a 'tickle' switch in line with my Oil Pressure Cutoff (no oil pressure, no pump) set up to prime the system. Works great. Also handy to check for any leaks after doing work before ever starting the engine.

Thanks, man! Didn't even know these check valves existed. Definitely need a couple for my old cars. Maybe I'll be able to leave the air cleaners on permanently!

Great idea & explanation. Im currently thumbing through a search to diagnose my 1980 gmc 454 with a holley carb. Came across your vid and have to see whats going on. Thanks!
