to many problems!!!!
 
first problem is im having carb problems, the nozzle that squirts out a stream into the primarys ive got a problem with it not spuirting out gas so it will run but it you can hardly give it any gas. but it will work sometimes it will pump it out. i took it apart and the accelerator pump looks fine. then when it does run good it give it a hard acceleration it coughs out acting like its running out of breath.. idk ive been having so many problems with my motor not running right i just need some good help...

fuel pump is good?
filter is not plugged?

in other words, the carb is getting a good supply of fuel?

gotta ask :thumbup:

First things first.
Tee off at the carburetor inlet and run a copper line back to the firewall, then up past the hood lip and onto the grillework (cowl) between the hood and the windshield. Mount a mechanical, liquid-filled fuel pressure gauge on the cowl temporarily and read the fuel pressure gauge as you drive. You'll need a steady 5 psi of pressure in order to fill the carb without overpowering the needle and seat, so monitor the pressure through the windshield as you drive. If it's too low, replace the pump or look for restrictions in the line(s) from the tank. If it's too high (over 6 psi), regulate the pressure down to 5 psi with a regulator or replace the pump with one that will limit pressure. Once you get the pressure under control, you can begin to test for other problems in the system.

when i take of the line it is pumping quite a bit of gas it seems to me, filter is not plugged, when i first start the engine as in it hasnt been started all day there is plenty of gas coming out of the nozzles into the primarys, then when i go to drive it it starts acting funny like it has no power what so ever and there is no gas coming out of the nozzles like its not getting enough gas into the fuel bowls to pump it out or something. i mean all the jets and everything in the carb look clean no sign of old gunked up gas or anything.

Again, follow my instructions in post #5. You have to test for problems one at a time and fix them one at a time.
