    2e engine po, bagong overhaul, bagong karburador. Pero bakit po ganon? Pumupugak po yung tambutso, inadjust na rin po yung timing at a/f mixture. Ano po kya problema? Sa muffler na kya? Ramdam ko po kasi pag naka upo ako da loob ng kotse at sa steering at accelerator yung pag pugak ng tambutso. Patulong naman po

    Questions:
    1 was it " pugaking" before the overhaul?
    2 what do you feel- vibration? Noise? Loss of power?
    3 is the symptom random or does it have a pattern?
    4 when does it happen? With engine warm or cold?
    5 if you place a strip of paper like peso bill at the end of the tail pipe, does the paper get sucked in periodically?
    6 does it smell like unburnt fuel at the tail pipe?

    A smoking engine does not necessarily dictate an overhaul, it might have been bad valve stem seals. Next time before giving way to an overhaul hungry mechanic, have cylinder leakage test and compression test done first. Compression test while cranking and engine running compression test usually determines if an engine tear down is necessary

    Sir jick.cejoco. before and after inoverhaul ganon pa rin po pugak, nafeel ko po sa vibration, random po sya. Mas malakas po pugak pag bagong start. Try ko po bukas yung sa papel. Matapang po yung amoy ng usok. Pag binuksan po pinto malakas amoy lalo na pag naka aircon.

    Your misfire can either be caused by mechanical problem but since you mentioned it has been recently "overhauled" you can rule this out if it was done right or ignition misfire. Check your ignition wires, plugs and distributor cap. So the overhaul did not fix the symptom, it got worse for a fee?

    Langya pwede sayawan ng katutubo[emoji1]

    Gawin mo muna ang dati kong suggestion tungkol sa ignition. Kung kaya palitan mo na ang distributor cap, rotor at spark plugs

    Cracked, carbon tracks, pinholes, worn out terminals, corrosion moisture retention due to porosity or age over five years. Imagine how many sparks per week in billions over time.

    Revisit the "overhaul" and do forensics to it. First, compression test, then, engine cranking vacuum test, and third engine running vacuum test. Have this done by a competent technician. There is a very big possibility your "mechanic" missed something during the "overhaul". Just replacing expendable parts is not overhaul.

    If the misfire is intermittent or random, try running the engine with fresh fuel from a safe container other than the fuel tank
