So just hose from the air filter, insert the hose up to the throttle and tidy purely spray what. Leave on for few minutes, engine start (4-5 seconds with hot gas. But it is normal I think because of all the brawn that is now in the throttle and with burned) and the gas again give whatever is pure spray. Few times neat accelerator - finished.
Note: Idle speed is the first time after cleaning increased (ca. 1100-1300). But disappears after a few kilometers back to the correct idle speed.
