Hello, I have the following problem… My Sym Allo, 50ccm, 4 clocks, which I bought as a hobby vehicle, does not start at all. The problem was that he has no suit and always came only weak up to 30kmh and then finally drains. Now he no longer starts at all. The spark plug is wet after every start attempt and in the suction nozzle it is also wet. I spark is there. Compression is with 11 bar I think, valves are also set. I tried with small but the problem also occurs with the 40s (smallest size). Original nozzle is an 82s. After this did not work I bought a complete new carburettor. Also unchanged. I have slowly the feeling that the ignition spark is not enough to ignite. Does not ignite even with starting aid. I am really at the end of my knowledge and please for a few tips. Thanks already
