oooh.....
later i play with the mixture screw and sees how it goes...

might be my previous mech....
cause the engine comes from japan where the temperature is cold and the choke disable slow... then the mech migh tune my engine when the choke is still on...


i also thinking spark plug problem..
(cause the vibrating seems like.. 1 or 2 cylinder not working)..
could it be spark plug problem?
cause the problem dissapear after the engine is warm... ?

hi...
yes... it 'shakes' when at idle and also at rev...
even i rev it high also it will shakes (with 'rythm')
vacuum gauge needle is shaking also, between 16.5 and 18...
really vibrate a lot...
so for the first few minute or so.. it is.. almost impossible to drive.. the car like not moving, the engine shaking.. then if i press the accelerator sometimes the car suddently accelrate ...

but everything went back normal when the choke start functioning..

hi all

my car have this strange problem that started few days ago.. hope someone here with experience can teach me... is there any problem..

each morning when i start the engine
the engine will 'vibrate' a lot, with 'rythm'
how to describe..
feels like a lot of vibration...
like we pull out one or 2 plug cable (When the engine runs on 2 or 3 cylinder)
that kind of huge vibration

then after a minute or so,
only the auto-choke start functioning,
and after the choke functioning, every things seems smooth
and after the engine is warm enough, everything is smooth also


so what could have cause this problem?
anyone here can help me??

information..
- my engine is A15, with hitachi 306 carb with auto-choke.
- last change of spark plug is around 3000km before.
- i live in tropic... where temperature here is not cold at all.. lately is raining season so temperature might drop 2 or 3 C
- i use my car on short distance everyday.

anyone can help me??

thanks..

oh.. i not change the radiator...
i thought the original one is enough.. :)

cause the fan is big and radiator fin area also big (bigger then modern car.. :) )

ya... so now i try to trace where will the engine be.. :(

i am from Malaysia....
i think my old engine must be in some scrap metal yard already.. :(

the mech sold my old A12 engine (still functional)..
now she probably somewhere in scrap matel yard waiting to be melted.. :(

the story goes like this
few months ago i change to A15
i told the mech my A12 temporary there
until i can hire a truck to move to my place.

then later these few months i've been bz,

yesterday night i call the mech
he said my engine together with other engine
is thrown away already.. :(

well part of it is my fault
cause i've been bz ..

now so sad,....

ocphangaz : nowadays weather here getting hotter and hotter, even if i drive at afternoon, the water temp will goes up to the middle mark also.. :) and mostly stay there

last time it used to stay constant at the 2nd mark..

oh.. thanks COUP1200
the fan does bolt into an aluminium thing and to the water pump..
later i try to spin it and see..
so if it is rough means i have to take it to the mech already...

ya...
might be the sound of fan also
but another B310 is more quiet.. :( strange... :(

the wind really big.. :D
how big.. it can blow sand off the bottom of the car.. :D
