carb was set up like this when i bought this jeep about 7 months ago. when i go wheelin, or any time i run it at high rpms the motor makes a loud sucking noise through the carburetor. It begins when i first give it a little bit of gas then begins to suck. if i give it around 50% throttle or it will rev up high then suck and do this repeatedly til i let off. if i hold it at around 10% it will make a loud sucking noise and shut off. if i try to drive like this it will jerk the jeep back in forth as i go down the road. I usually can get it to stop if i hold throttle at around 1000rpms right befor it dies then give it gas and there will be a loud pop coming from the carb and i can drive as normal.
this is my first carburetor and I'm still learning bout them.
thanks for your help
