I did all that was suggested. Remove the plugs, check magneto, re-align...etc. Wow...the engine starts and the wheel did not locked up. I do not know what I did in the beggining why it did not start from the first time though...But I felt so relieved when it starts...
Now, here is another issue. The bike does not idle! When I release the throttle the engine stops. When I turn the throttle half way the bike does very minimal idling. It seems out of air and chocking. Then when it is in full throttle then it goes to full RPM and the bike zooms. I check the carburator slider and made sure the pin is inside the hole. I am pretty sure of this becuase the slider dropped all the way to the bottom. Then i checked the spring and the throttle return it seems fine. Any idea what is going on? Thanks. |

| | Re: Bike Stops when Starting Is the choke lever down???
How much oil did you mix in the gas???
What's the plug gap?
Also, turn the idle screw in to keep the idle up.

| | Re: Bike Stops when Starting Here's a good one that I just thought of... Is the carb needle 'C' clip above or below the little washer with the slot in it?? The washer is supposed to hold the needle down! |

How much oil...16.1 this is what the instruction says on my kit
Whats the plug gap? I am totally clueless. I do not know the specs. The kit instructions do not mention this.
I do not know where the idle screws are? where are they btw?
How about the choke lever? is this the white lever? if so I had it down when starting.
Sorry I am really new to all this things......

Sorry I am really new to all this things...... | Ok... lets go through these one at a time...
16:1 is way too much oil!!! Use 24:1.... 16:1 is for the old days when they used to mix motor oil in the gas!!! now a days we have 2-stroke oil, & you don't need as much of it in the gas!
Next, Plug gap should be .030 ish.
The white lever is a fuel shut off valve. point it down for "on", (sideways for "off") There is another metal lever just above that one... that's the choke. point it down also!!!
Try these things & see how the bike runs. |

| | Re: Bike Stops when Starting hopefully you got her by now, but if not and you followed the advice of venice,.,,.try re-adjusting your clutch pack,.,.my last build had simular clutch issues. But first check sprocket alignment and Also de-burr the pinion sprocket as it can lock up the chain during rotation. It also may have the piston wedged at TDC due to the squish so use caution when you assist it's cycle down, you may just remove the head and check for shiny areas or flattened lip on the head where improper milling may have taken place, or just an over-torqed head bolt. I concur on the ratio, all my 2 strokes run 927 @ 32:1 with your set up it's fighting to ignite fuel and will almost always foul out or just puke unburnt fuel all over your shoes,.,.GL Stuk
