Are you using the new cvt you ordered ? If so did it come with the bendix bushing installed ?

New starter new bendix new bushing new battery . In this video you can see the gears moving but still no turnover . youtu.be/t1trlMg93cU |

Somebody should copy & paste the diagnosis advice from the last few threads. It'd save alot of typing

Your Bendix is doing the job it was designed to do...it is meshing with the teeth on the crankshaft gear just fine. Bill |

Why is it turning so slow on a fully charged battery

A good battery should come back to at least 12v after cranking. The battery might be new but it is not fully charged. I will give you props for the cover mod so you can see inside.  |

Why is it turning so slow on a fully charged battery I don't know...it could be several things but, I watched you video again...several times actually, and...I believe the bendix is only supposed to engage with that large gear once it spins up. The act of spinning forces the bendix to extend out and mesh with that gear. What I see yours doing is staying extend out and in contact with that gear even when it is spinning slowly or stops spinning. That is not supposed to be like that...otherwise...when it does start, your starter motor will be turned at high speed by the crankshaft. I have no idea why this might be but, the action of your bendix is not like it is supposed to be. Maybe some of the others here can tell you why that might be. Bill |

You could take the spark plug out to see if it will turn over faster or if something else is binding up the engine.

What do you mean sr? There's nothing wrong wit petcock? Cylinder hydrolocking? A bad petcock would allow fuel to continue to flow, from gravity, when the engine is off and the scooter is parked. If you have a not so good seal on your carb needle, gas can and will flow over from the bowl into the cylinder. Air compresses, liquids do NOT which is the principle behind hydraulics. If you do not have much room in the combustion chamber, it would not take all that much liquid to hydrolock the engine. When this happens in a top fuel dragster engine on just one cylinder, it will cause the entire crankshaft to exit the engine block through the bottom and end up on the ground. Nothing like that will happen here at all...just giving you an extreme example of it. All it will do to a scoot engine is make it very hard to turn over or, stop it from turning over at all. Bill |

Bill I took bendix out adjusted it n put it back in it started now it won't idle but it started so happy |
