Well if it corrects itself when you use the choke it must a) be running to lean or b) not idling fast enough. (Or both!)

Unless the petrol smell is from a leak somewhere which is causing fuel starvation, corrected when more is delivered by use of choke.

on a new day bifor start a car pull chok then start car after 1 or 2 minut off it - but my car has some miss - if i pull chok engine not miss - when i paddel cluch engine stop- ideill speed not enough - some time when i raise engine engine sound 'Gad.......Gad......Gad.....' like miss -but if i pull chok not sound like that- petrol smell come out from cylanser in back of car

Valve gaps all ok? We really need to see compression test results......

[Sandun]

how to test it ? What is the compression ?

I think pulling out the choke to test that the miss happens then stops, maybe causing the petrol smell.

Did you say you have tried speeding the engine up and it didn't cure the problem?

You need a compression tester - like this http://www.ebay.co.uk/itm/PETROL-ENGINE ... 231a3527b5
Remove all spark plugs, screw the tester in to one hole, prop the throttle open and crank the engine over for 5 seconds. record the reading - reset the gauge, and repeat at the next hole - until you have all 4 readings. Should be all ~ 150 psi.
