Honda Unicorn 150 / Engine problem

1 India Review updated:

I have a problem with my Honda unicorn the bike. The bike starts but the moment I accelerate the engine stops. In the rainy season, this gets worst. Some time during travel if I change the gears the moment I leave the clutch the engine stops and jump-starts. The service center does not seem to have an answer to the problem. I have tried changing the spark plug, cleaning the tank, cleaning the carburetor, changing the diaphragm in the carburetor. Engine de-carb. Nothing seams to work. The worst thing is the problem is not consistent. Does not happen all the time, which makes me look like a fool at the service center.

Can any one advice.

    @sanjay123 It may be because of some water in carburetor. Trying draining petrol from Carburetor it may help in draining water particle from it.

    I have the same problem. There is not starting problem it starts in first kick and first self. but when I start to warm up engine and throttle more there is some kind of sound like tik and the engine goes off. And then the kick compression goes very low and it wont start neither by kick nor by self and the only solution is to push the bike to start and after that everything is normal again. Whats this problem??
