Hi, Today i tried to start and run in my brand new Marder with Zenoah 26cc engine. She tries to start but will not run as i seems to be over fueling. I checked the needles settings and they were correct according to manual. I also tried them at 1 1/2 turn high and 1 1/4 low with no affect. The only way she will start if you pinch the fuel line and pull starter. She will run for about 5 seconds and when you release the fuel pipe it will flood itself! I managed to get it to tick over by winding the low needle to 3/4 turn from closed and the high 1 turn from closed... but its still miles too rich and will not respond to throttle as it bogs down and then stalls.... advice please as im new to petrol
