ok guys, its been awhile since ive posted. So... I need more help. Heres what I did so far. Kept having bogging out problems after I put everything together. So, I got a new carburetor. Same problem, found gas in my intake, got a new fuel petcock. Checked all my lines for leaks. All of those are good. Now, no gas in my intake. cranked right up with good high idle. twisted the throttle... and dead. Again.... Please HELP! also, messing with the idle screw doesn't seem to help.

Valves that are too tight will generally make for hard starting, not bogging or dying when the throttle is opened up. Most bogging is caused by a too lean mix that occurs when the throttle plate opens and allows air to flow. Air having lower density, will get moving quicker than liquid fuel, it having higher density. The result is a blurt of air with too little fuel mixed in, AND, bogging or stalling. Fix the mix, and all should be good. Either the idle is too lean, or the mid-range(pilot) is too small, again, leading to a too-lean condition as the carb goes through its stages. Some have an accelerator pump that squirts fuel into the venturi, right before the throttle plate(air cleaner side), when the throttle is opened. They have a flat tab(longish) that poked downward on a rod which operates the pump, causing the squirt. If the tab does not touch until after the plate is opened some, you'll likely get some hesitation or stumble upon acceleration. tom

This is what happened. It fired up. great. before I could adjust carb. a heard a clang. and then all hell broke loose. The starter came out, and then the white plastic fan thingies, began slamming the kick start, causing IT to jump and bang everywhere. Immense noise ensued. You could here the starter banging around and slamming. Also, during this. the engine revved up extremely high, and began to jump and buck under me. Working splendidly, at the worst time. So anyway, I got it cut off. pulled the case. The starter not only, popped out, but stays engaged now, at all times. I put it all back. just to try and see what happened. Guess what? The motor bogs again. and the starter stays engaged. When it popped out, the thing ran great. So tell me, mighty scooter wizards. What in the actual **** is going on. im now 350$ into this thing and mad.

I wopuld look closely at the "Bendix" drive that connects the starter motor to the variator. It has a gear that rides on a spiral which slings outward and engages the variator when the starter motor spins up(quickly). If that sticks, it will keep the variator engaged with the starter motor, and spin the starter motor at unreal rpms, which will perhaps turn the starter to a burning hulk. (melted bushings... etc) Check the bushing at the tip of the Bendix in the CVT cover. It may be gone, or worn out. That could allow the Bendix to get jammed into the variator even if the Bendix was working perfectly. The bushing should fit snugly around the tip of the Bendix drive. A little loose is OK, but not floppy loose. It will likely not run properly if the starter is jammed up... The Bendix should spiral out and spring back when moved manually. If it jams, get another, or take that one apart and find out why it doesn't work & fix that problem. tom

The gear at the lower end of the Bendix should rotate CCW as viewed end-on, and should spiral outward so the teeth engage the variator. If it is gummed, and won't move freely, snapping out and retracting, then it may be cleaned and lubed with light oil. WD-40 might clean it up enough to operate freely. You may be able to take it apart for closer inspection and cleaning. I don't think there's much inside, as it is more or less an 'inertia' operated mechanism. The starter motor must spin the thingy real quick, which catches the gear asleep, unaware, so it will try to stay where it it, and not want to rotate.(inertia will make it want to stay asleep) But, the starter spins the gear fast, and the gear staying still is forced to ride out on the spiral ramp, and engage the variator. As it engages, it will get 'stuck' by teeth friction, and stay extended. And, the starter motor will continue to rotate, hopefully cranking the engine over. If gummy, the Bendix will not ride out on the spiral ramp, and won't engage the variator teeth. If the starter motor spins slowly, inertia will not be enough, and the Bendix will also stay put, not ride the ramp, and fail to engage. Maybe dunk it with brake cleaner(another word instead of dunk that begins with 'd') and then splash in some WD to see if it will free up. New is nice, too, but delays operation... tom
