Sputters out

[baller5040]

Ok so i am still having a hard time with my truck. Its sputters out alot now. I have changed the spark plugs and the spark plug wires. I blew out the fuel lines to make sure there is nothing blocking then. I also took the top off my carb cleaned it out with carb fluid so if anything is blocking the jets it would have cleaned it out (i hope). So now i'm down to two different things one take the carb off and rebuild it something might be stuck in the jets and wont come out second the filters in the tanks are clogged up and wont let enough pressure go through the lines. If any one could please get back to me ASAP about this it would be great.

I had a problem like this a while back it turned out that the positive wire to my starter grounded out to the exhaust cause the heat melted the covering and grounded it out so check and see if that Heaney wire is grounding out or if any power wire is grounding out

Try taking your carb apart and making sure the float bowl is working properly. It sounds like you're starving for fuel once you really open it up and that would be a likely culprit. It doesn't take much for the float bowls to decide that they don't want to work right.

I knew a guy who had a very similar problem with his truck; it would run fine at low speeds, but once he tried to use it to pull his trailer, he couldn't get any power out of it at all. Turned out it was his (recently rebuilt) carb acting up. Sometimes even new parts go bad.
