i have 1993 toyota corolla xe. i'm experiencing hard starting especially in the morning or after a prolonged (4 hrs or longer) period of non-use. engine runs fine when it is warmed up. my car was submerged during ondoy. in the past 2 months, i've had the following done:
1. replaced 5k carb back to 2e big body carb
2. installed brand new original hi-tension wires
3. changed air filter element/fuel filter
4. changed alternator -higher amp surplus (original - overhauled once in 2010 - finally gave up)
5. replaced sparkplugs
right after the alternator was replaced, noticed that the idling jumped to 1000 rpm. after adjusting idle to 800-850 rpm, noticed that the air-fuel mixture was too rich when we took a look at the carb (taking out the air filter element) - gasoline was covering the carb. this was about a month ago, fc was better, but cold hard starting became the norm. i've tried all the advice - like stepping on the accelerator pedal before starting (which worked before the alternator was replaced and air-fuel mixture was adjusted) but as of now, the first try to start always ends up in the engine dying (nalulunod). after getting the engine started, i should not put my foot on the pedal or try putting it in gear or else, the engine will die. also, i noticed that when i changed the sparkplugs, there was gasoline in cylinders 2 & 3.
what could be the problem? the carb ( i bought it brand new last may 4),my 5k carb worked ok except that i wanted to get my car back to original specs. need help.
