Air sound coming to the gas pressure

My friends car 206 cc 1.6 110 hp
For a while, when the gas is hit the first time, there is an air noise, it seems like the car will drown.
It turns back to normal after 1600 revolutions, there is a serious low traction spark plugs changed, induction coil is provided, I read in a few places because there is a possibility of a westinghouse or something.
A master said that the valves seem to be burnt, he did not look like a person of his job, he said the price of 1000-2000 lira
My eyes are afraid frankly, Westinghouse, how do we know? There is not much trouble in braking.

Hi;

I was told it has to change before

My teacher does not have a problem with the westinghouse about the transfer of the vehicle. the master says that it burned the burnt valves right off the road, Let's take a look at our throat butterfly as our mert friend says. Let's use a little bit of gas in the vehicle without dropping it under half a tank, bro.

I am having the same problem right now. How can you fix the problem? Ugrcn 2017-08-29 20:34:07

My teacher suddenly, several times intermittently, pull, point, pull, puaff puaff is coming from the throat butterfly. This is not a problem. it has neither traction nor anything else.

When I go, I press the gas to the end, it does not eat after 4000, it does not increase in speed.
