who know what's the problem ?
my car seems not very smooth . the car body jerk a little when idle u can tell it is like misfiring or someting .
the jerk is not very obvious but it is like it happen in a fix interval or cycle .
I got a vacuum gauge installed it shows the pointer vibrate between 18-20inch .
could it be the distributor problem ? or there's a leak at carb ?
Recently I just change carburetor and spark plug .

how's your tuning? idling below 1k ?

One of the major problem is finding someone to check vacuum leak for you . There's no workshop know how or want to do it .
When u ask them they will tell you nothing wrong and there wont be any leak cos the rubber tube can last 100 years and if there's a leak you can hear and your car will not run and etc nonsense.

who knows why there's a coolant tube connecting to the carburetor ?
why autochoke need coolant ?

Who know where is iswara PCV located ?

hi bro , here afew more questions .

1.the water temp rise means the coolant temp rise ? autochoke need hot coolant to push it open ? isn't coolant temp is low ?
2.Is there pcv valve in lmst saga ? if so where can i buy one for replacement ?
3.if you turn the distributor to the right side until it can't be turn anymore and then tighten the srews is that the max advance timing ? will it damage the engine ?
4. why my car need max advance timing to become smoother ?

anyone here know how many vacuum inHg needed to operate the advanced timing unit ? what's the max vacuum inHg ?
I tested mine, max vacuum is around 8 inHg , is the vacuum port functioning normal or too weak ?

Are you sure or not , bro ? If your one is 15 inHg then that's mean my carb got problem already .
