Coure Starting Problem

[haseebahsan88]

My car is (coure 2006, manual transmission). If my car miss first self then it takes around 10-15 selfs to start and when the car starts it misses and gives grey smoke until it heats up properly. After heating up, it don't miss and grey smoke also vanished or converted into white smoke. My mechanic have changed plugs, point, and cleaned the carbunator using carb-cleaner spray. Battery is also new. Changed two mechanics in last 1 month, but no one is able to figure out the main problem.
Any help in this regard will be highly appreciated.

It could be because of incorrect valve clearance or leaky valve,get it checked accordingly.

Re do valve clearance ignition timing breaker point spark plug gaps and carb mixture adjustment. For carb mixture turn it full anti clockwise till the point car stalls then move one rotation and start car then move one more rotation or the point where engine smooths out and check that advance vacuum works properly.

Thank you, for your replies.

In my opinion, white smoke is very critical, poor engine compression will cause long starting.
Check your vehicle cylinder compression Dry and wet condition, it will revealed you either problem with valve seal or piston ring.
if each cylinder compression vary other one it mean it is not good for engine.
Closely monitor your engine oil consumption.
May be engine need over hauling.
