good day.

here's my story. medyo mahaba pero please bear with me.

we went on a trip to cavite last saturday and was already on our way home. we stopped by a shell gas station for lunch. when i got back to thje car, it just won't start. the in-house mechanic told me na yung fuel pump ang problem. he managed to repair the pump, just enough for us to get back home.

i got a replacement pump and had the fuel filter changed. my mechanic adjusted my distributor to "have a better timing" daw, and further adjusted my throtle, incresing my idling. since i'm not aware of the consequences i just let him do the adjustment. he's quite respected in the neighborhood, being a senior mech at that.

then the problem began.

during my test drive, the car was a little rev-happy, shooting up past the 2000 rpm mark quickly at 2nd gear pero parang walang hatak. when i got to open road and was already on 4th gear, the car was jerking forward, parang sinisinok yun engine ko. i decided to get back home pero halfway on my journey my RPM dropped, and eventually my engine stopped . i was lucky it fired up again to get me home.

my mechanic got to me later and adjusted the distributor again (im on a carb-engine). the test drive now feels better, may hatak na ko sa 1st to 3rd gear, pero still shaky. when i get to 4th gear and stepped on the pedal mabilis acceleration, but when i get to 60kph the engine refuses to accelerate, the jerking returns and my RPM is pegged at 2000. ayaw nang tumaas ng rpm ko.

my mechanic said baka daw may problem na timing belt ko (that was replaced for only a year and a half), and wants to open up the engine to check the belt this weekend.

i want to solicit your opinions on this matter. the car was in tip-top shape before i had trouble with my fuel pump. timing belt nga ba problema? are there other factors to consider?

thanks in advance and more power to all
