I don't understand anything! My idle suddenly goes way low, and engine sometimes stop, it's running so low that the gear lever is shaking out of my hand(manual) I've found out this: It's not the magnet valve for the idle, i've tried with it and without it. This is what happens: idle is fine, i rev the car in neutral to around 3500-4000. when it drops back down idle is messed up, extremely low. If i restart the car everything is fine... I can do this like 10 times and same thing happens. I replaced the ignition cables, spark plugs, coil, rotor/cap, changed out the points with ignitor. When idle goes bad and i trie to rev the engine it runs extremely rough like i's on 3 cylinders, it also rund rough when i drive it, but not so little power that i would suspect only 3 cylinders working, and it may suddenly start to run good! I'm starting to think there may be som internally wrong with the engine, because i've been trough the carb (zenith 175) and igntion several times.

Need help on this one can't seem to get anywhere
