Your going to have to post those pics elsewhere. Your Myspace profile is private, so we can't view it without being a "friend". Try putting them directly in your post

If you're using firefox, right click the pic and then click copy image location then paste here. If using IE, right click, click properties, then copy the link there and paste here.

Shutter valve. It leans out the rear rotor to prevent backfiring when decelerating.

I don't know carbs but not accelerating is probably loss of fuel, make a video?

The shutter valve cuts fuel thus leaning out the rear rotor which stops the backfiring from the fuel being thrown n the exhaust, I think thats how it works exactly, you'll get popping backfires without it.

I don't think it'll stop acceleration at all, as said iono carbs much.
