Ok, so I swapped a 2.3L pinto engine into my 1953 jeep and am having problems getting it to run decent. It starts right up and idles perfectly, but if i punch the gas, it just wants to die, and if i actually hold the throttle all the way down after punching it, it will die on me. Another thing to note is that if i increase the throttle slowly, the rpms will pick up and it will run pretty smooth at 4,000 rpm or so. I just rebuilt the carburetor so i doubt that anything is plugged in there, although i could be wrong cause i didnt really know what i was doing. Also, i am using the stock jeep fuel line from the fuel tank to the fuel pump, which is a 1/4 inch line. My guess is that the fuel line is too small and therefore the engine is not getting enough fuel when it needs it most (when i punch it). I have a inline flue filter that is always only half full. Should it be completely full all the time? Any thoughts or ideas??
Fuel filter does not need to be full. Look down carb bore when operating throttle make sure accelerator pump is working meaning you see fuel dispensing from accel. pmp. jet if ok check ignition timming + point gap if older engine and if that doesn't help ask Kim ;D . Fred :)
What about the fuel filter being clogged? the fuel tank was far from clean (i tried to wash it out before re-installing it but im sure i didnt get anything) And it seems that the engine ran a bit better when I started it up for the first time than it does now which makes sense as far as a clogged FF goes.
Sounds like a carburetor problem to me. A filter is cheap, you could try it but I dont think thats the problem. My 76 does the same thing you describe when it is cold, except it wont idle. Once it warms up its fine.
I think you have a vacuum leak somewhere or an otherwise lean condition caused by the carburetor.
Ya im really hoping it has something to do with the fuel line or fuel filter rather than the carburetor because i just rebuilt it and it still has the same problem. Not really sure what to check if replacing the filter doesnt work. Might just have to buy a new carb i guess.
