two q's bout scoot

[49ccsofdestruction]

first q. yesterday morn my scoot (TNG LS49 1e40qmb) started, ran for a few minutes and died. i restarted and it ran for half a minute and died and would not start from then on. it ran fine the day before and started up when i returned from work and ran fine. i'm thinkin stuck float in carb?
2nd q. i looked at my variator and saw the wear pattern on the pulley from the belt. it stopped short of the outer edge by 1/4". is that a good indication the variator has a restrictor washer in it? if not what can be done to get the pulleys to come together more so the belt runs on a larger dia.? i'm trying to squeek some performance without going mod crazy. thanx.

1) If it doesn't do it anymore you could clean the carb to be on the safe side and re-adjust the idle mixture and speed settings if necessary.

2) It's actually normal for the stock setup to leave room on the variator for more travel. If it has a restrictor you should be able to see it. Look into the middle of the pulley and it would be between the outer half (fan) and the drive boss. You could experiment with modding the variator to allow the two halves to close tighter. If you do this, I suggest going a little at a time and you should understand that mods like this don't always get the result you want. I found that with some mods even the stock 90cc didn't want to pull the extra "gear" I created by allowing the faces to close tighter (of course I'm also heavy).

hey thanx for the answers. always helpful. i guess i'm taking my carb apart this weekend. as for the variator mod i read you saw none or less belt travel after filing the pulley. could it be the stock angle on the face of the pulley changed and no longer matched the belt angle? would this also be cause for less contact area between belt and pulley? maybe thats why u never saw the marker disappear. i drew a really cool illistration on paint but i dont know how to post it in this reply.

I didn't change the angles of the pulleys (other than in the center), so only the distance apart would change at speed. I'm not exactly sure what was up there.

Ah. Thank you for posting that. After you said that I went and checked and somehow I had disabled attachments in this section for all but staff so I never noticed. Should work now.
