Hello dear colleagues, I hope once again for your advice because I just don’t know what to do. I bought a beeline qt50 used to it. It worked for 3 days and then gave up the spirit after about 100km. It didn’t start at all. Sparkling plug cleaned, no success. However, it has sparked. I cleaned the carburettor, also no success, I bought a new carburettor which also did not bring success. I re-set the valve games, I have m It was all ok, with approx. 6.2 bar. Battery changed – without success. Motor turns, but he just doesn’t want to start I really don’t know what to do anymore. I also changed the petrol tap and petrol filter or the hoses which of course did not bring success. Do you still have ideas what I could do? The only thing I tried with is to replace the spark plug, because I have a spark plug. or do you think it can still be broken? Would be so grateful about an answer
