my 87 samurai has got me at a dead end. it will run fine for a lil bit but under load it runs rough then will die out and i cant give it any throttle. ive rebuilt carb, new fuel pump, filter just about all new now and still cant get it to run. when i go under the hood and tap on the inline fuel supply to the carb it will run again for a little bitt but then when i go drive it it will die again.
