So the qjet on the truck I built out of garbage i found in the garage as a self imposed challenge.
I completed it and passed. However, the choke pulloff takes about 3.5 years to disengage, I still have to hook the electric choke up, (does get warm enough to come all the way off fast idle, egr hole in the carb pad helps with that I think). I found the accel pump in a box (I think it's about 40 years old) of junk parts, and the float may be soaking up fuel. Plus I had to fight the power piston to get it to stay long enough to get the cover on because the retainer is fubar. Also the fuel filter looks like it's been under a fridge for 40 years. All those parts ordered from quadrajetparts.com.
Other than cold starting it runs pretty great besides the damn thing gets literally 2.25 mpg, so either the tweaker installed tank is leaking, the 7.6:1 compression, cam retarded 5* from 0 from factory 160hp 390 is a heavy drinker, or some meth head is following me around and stealing my gas. Ive checked everywhere for leaks while running, not running, after sitting, just after shut down, nothing.
I have yet to check the plugs, that will tell all. If they're clean, there has to be a massive leak I'm not seeing or something. lord. I get these things got like 8 at best new but 2.25 is abysmal.
