Ok i got a problem with my 83 when i just decided one day to clean the little screens on top of the carb. Um there the ones that the main and return fuel lines go into to flow gas into the floats. Well those screws that have screens. I cleaned them and put them back on and my damn car started then started to bog then died after that it doesn't want to turn over. But before all this mishappen she ran ok. Man this sucks. Does anyone think that maybe when i took off that crap on the screens that maybe there was some crap in the fuel lines and finally after being cleaned maybe could have clogged some other crap?
