Easy starting is one of the great benefits of fuel injection.

Not sure? Post a picture of it the next time you have the cover off. | | | Re: IF I don't start the van every few days, I must add gas to the carburator ? | Joined: Sep 2016 Posts: 90 journeyman | journeyman Joined: Sep 2016 Posts: 90 | I have this hard starting problem. I had the Quad jet rebuilt, he fixed several problems, drilled out the choke and replaced the rod. Sealed the bottom from leaking, replaced all the parts in it. Still really hard to start. I suspect the cannesters could be plugged or even the lines could be cut that run to it. My thoughts are to run an electric pump with a switch. Turn it on let it fill the bowl , start engine and turn it off to run. Any thoughts on doing it this way? Will it work?. My 1947 BeechCraft Bonanza had a hand pump 3 to 5 pumps then start slowly pump while starting till the engine pump caught up then secure hand pump. Worked perfectly.

The only other thing I feel it could be is the choke is junk and misadjusted, possibly a very low float level
When in doubt..get the sawzall out..

Or leave the plunger off,you should never have to prime a q jet..the fuel from the bowl is going somewhere,after reading your post again I am leaning toward an accelerator pump

2. The fuel pump is brand new and seems to work great.
It can be more involved than that. A mechanical pump has a one way valve that prevents fuel from draining backward. I just had this problem on one of my projects. The fuel pump was almost new but when you blow through the outlet you can feel the air passing in reverse. Not a lot but that teeny bit was all it needed to cause a problem when sitting more than two days. I got another new pump from the parts store and tested it. Stopped up tight. No more long crank time trying to get fuel up to the carburetor. | | |
