    The Briggs & Stratton 6 KM 190cc OHV engine starts on a cold engine, however, after warming up and turning off, it cannot be restarted. Then the candle is dry, it has the color of coffee with milk. So far, I have replaced the ignition coil, cleaned the carburetor and nothing helped. Where else can you look for the cause?

    If the candle is dry, look for a problem in the carburetor. Have you tried to pump with a hand pump before starting on a warm engine?

    The carburetor has no hand pump, it looks like the one in the picture:

    I tried to water the fuel from the syringe directly into the carburetor and under the candle but it did not bring any results.

    Replace all gaskets before replacing, clean the surface thoroughly and screw tight.

    I did as you say, but it's the same every time. I will try to adjust the valves but I can not find what should be loose.

    If your Briggs is a Chinese fake, unscrew the head, move the piston back and check with your finger if you feel the threshold on the cylinder. I assume that yes, I also had the same situation. The mower landed on the scrap. , Briggs's perfect fake lasted half a year before she ended her life.

    The engine is probably from 1998, I don't think it is a Chinese fake. Or maybe I'm wrong?

    And how did it end, Przekrzych? Did you find the cause?

Topic summary

LABEL_AI_GENERATED
Briggs & Stratton 6 KM 190cc OHV engine starts cold but will not restart when hot; the spark plug is dry and light coffee-colored. Replacing the ignition coil and cleaning the carburetor did not solve the issue. Suggested checks included carburetor fuel delivery, priming on a warm engine, replacing all gaskets and cleaning mating surfaces, and inspecting valve adjustment. One reply also raised the possibility of cylinder wear or a counterfeit engine, but the engine was believed to be an older original unit.
