The car is mehran 2006 60k driven, driven on 10W-40 till now. Plugs wires point were changed 4 months back full tuning was done. But now my car is giving starting problem, i drive on petrol not cng. It doesnt start on first self, it starts on 3rd and vibrates and shuts off. Whats the reason behind this, it vibrates alot and i have to choke it for 5mints to get engine stable after it gets normal. Experts advice required.
blockage in petrol pipes ,,,,,,,,,, or need petrol filter change ...............
When the choke is defective or not adjusted properly, it can make an engine hard to start. The engine may also stall or die after it is started. When the engine is first started, a very rich air/fuel mixture is required because cold fuel vaporizes slowly. The "choke" at the top of the carburetor provides the richer mixture by closing and "choking off" the carburetor's air supply. The choking effect also creates an area of low pressure inside the throat of the carburetor that helps to pull additional fuel through the main metering circuit. At idle there isn't enough air flowing through the venturi to pull fuel through the venturi discharge nozzle. By temporarily choking off the air supply, however, manifold vacuum rather than venturi vacuum helps to draw the extra fuel through the main metering circuit. When the choked engine is cranked, fuel is pulled into the engine through the idle port, the transfer port and the main metering circuit. Combined with the reduced air supply, it creates the extremely rich mixture that's needed to start a cold engine.
Petrol lines are okay and fuel filter was also replaced with oem one 2 months back and car is giving around 14-15kmp/l. mileage is also good but car has bit starting problem although it has volta 50 battery replaced in april 2013. I dont know much about cars what should i go and say to mechanic about it as many of them are rips would say me to clean or service whole carby, but i wont coz my car is giving good mileage and engine throws water means mixture is good. What is the actual problem or what should i say to the mechanic. Several times i went to 3s guys they say that sir gari chor jaein sham ko le jaein even if it is a small 5mint work. The temperature in morning is quite low like 5-6C so this also makes an effect but on petrol car should start flawlessly.
Ok.......get your car tuned...........tappets need to be adjusted.
Seems like timing problem
Just came back from Suzuki Islamabad motors, they tuned the car completely tappet were set and timing was set through timing gun, they said timing was badly out. Engine tappet seal was also leaked which was replaced by oem one. Now car feels much smoother but they told me one thing that mehran has 2 bad problems that ac doesnt work effectively on this car and it has starting problem in winters. I told them that i use zic 10w-40 which is not thick oil they said me that use sgp oil 10w-40 which is even more better. I didnt take it to mechanics whenever i tell them any problem about petrol they say carby needs service needs jet change needs butterfly etc. Suzuki techs told me that i should replace my plugs and point after 12000km and plug wires after 30000km to ensure better performance and get it completely tunned after 10000km.
I will replace my plug wires with 8mm and change it to the coil which comes in cultus which is powerful hence provides more current better acceleration.
These strange problems come in Suzuki Mehran! I'd a similiar problem in my mehran. It used to start on the very first self within 2-5 seconds and if you miss that chance it used to take 6-7 self to start ... I always used to start it on the first self always!
never go for SGP oil it suksbetter stick to zic i kept mehran for 7 years and every winter seasion i used to have a morning exercise pls also get a small battery charger for 500rs when mehroo gives u troubleuse that to charge batteryand start it
8mm plugwire se itni choti gadi mein koi farq nae parhne wala dont waste money bhai! jahan extremely high voltage coils are used such as MSD's etc wahan thick plug wires kaam atay hein! tumari gadi mein koi farq naeh parhne wala
Y so negative about small cars i got Alto and mehran and 8mm are 700 rs for themAnd i took stock ngk off my new car and put them Farak parta hai
