Hello everybody, I hope for help here. I restored a TLM 200 2-stroke, replaced the missing carburetor with a Keihin PE24 from China (main jet 112, secondary jet 38, needle 2nd position from the top), spark plug NGK B6. I can't get it to run properly, with choke it revs way too high, without choke way too low and dies out. When trying to turn the idle gas higher, the engine suddenly ran at full speed and could not be stopped even by pulling off the spark plug connector... only after turning off the petrol and closing the exhaust pipe did the engine finally stop. Does anyone here know the original carburetor setup? Thanks in advance and greetings from Aachen, Germany Thomas
