HELP Zongshen LZX200 wont start!
g'day guys, i bought this bike off a mate, he rekons it was screaming when he started it, and wouldnt idle..
so i took it all apart, pulled the carby, fully cleaned it, put every thign back together, made sure the needle, and slide was in the correct position, and now it just wont start..its kicked a tiiiny bit twice in 2 days... It has a spark, it has air, and the exhaust isnt obstructed, and its getting fuel (i pulled the plugs a few times and it was wet and black) so im absolutely stumped... it has a 'sheng wey' carby. how far out do i unscrew the idle screw, and how far out do i unscrew the fuel/air mixture... any other tips? this is reeeally frustrating... thanks a heap |

Don't worry too much about the idle screw until it runs. The idle screw is only opening the throttle slightly; you can do that manually.
Tighten the air / fuel screw in gently (counting the number of turns), and back it out 1.5 and try again. Have you replaced the spark plug? The stockers are junk; go with a genuine NGK. Cheers!

Just to be sure fuel is actually passing through the carb, drain the bowel with the drain screw at the base of the carb. If that runs freely, you defiantly have fuel. I know you think you have fuel but this will make sure.
I am not sure you can get that bike to run with a stone dead battery, i would like other opinions on that. |

Like my Qingqi, it might have a "DC-CDI", that is better called an ignitor or igniter. This draws its power directly from the battery's 12 VoltsDC. A discharged battery will mean no go.

If your motorcycle is difficult to start, check the compression. If the compression is low, check the valve clearance. Spud
