77 F250 400.
Truck sat in my driveway not moved or started for two years.
Some gas and a good junkyard battery it fired right up. Started the 7 mi trek to the old house and about 2 mi in it quit. Keep wacking the carb and it would run good a little further then putter and die.
Ok so fast foward to a few weeks ago....i finally got around to getting the carb off and rebuilding it. Stripped it down, replaced everything that entails a rebuild, cleaned itl blew it out, etc etc.
Put it on the truck, primed it, hit the key it fired up and ran for about 15 seconds then died. Would not start again.
Waited about 30 seconds, hit the key fired up ran 15-20 seconds and died....did this over and over. Pulled the cover off the carb and seen there was barely any fuel in the bowl.
I had a new fuel pump so for poos and giggles i changed that.
Same thing.
Now when i rebuilt it i set the mix screws to initial and also set the float to proper level. But i pulled the cover off and set the float up higher....damn near as high as itll go.
Now it will idle good and strong but if you sit there and hold the accelerator at about 2000rpm itll run maybe 45 seconds and quit....just like you hit the key to kill it. But then will immediatly fire back up.
I cant set the float any higher, and i can suck the fuel line by mouth and pretty easy get a mouthful. So i dont think theres any obstruction. Filter is also new.
Ive never had a duraspark module fail....could it fail like this? When it is running it sounds good and strong.
My gut says its fuel related but when it dies it just dies....not like it did before where it would putter and stumble first like it was running out of fuel.
Kinda at a loss here....any ideas?
