    -wala sa timing
    -tuneup or DIY
    -mura lang. pang mcdo mo lang

    alternatively,baka wala na sa lapat ang cylinder head etc. this will cost more...pakita mo na lang sa mekaniko na competent

    katok or tope = engine knock = pinging or hammering = predetonation. it sounds like there's a hammer inside the engine, and that's exactly what it does. predetonation acts like a hammer on the pistons, causing major damage to pistons, connecting rod, crankshaft, cylinder head and cylinder liners.

    causes: too low air/fuel ratio, too low fuel octane used, bad ignition timing.

    fix: adjust carb so a/f ratio is not lean, use higher RON fuel, adjust ignition timing. cheap lang yan, cost of a tune up kung need ng adjustment ang carb or ignition timing.

    but the cost of fixing damage from engine knock is high. spell "overhaul", o-v-e-r-h-a-u-l, overhaul. mura pa din? spell "new cylinder head", or how about "change engine"? wag na haba nun hehehehe...

    Yan din ba yung kapag cold start, malaki ang standard deviation ng fluctuation ng revs per minute pero kapag medyo mainit na nawawala na?
