You may be a carburetor cleaning. Clear it completely and Czech that has a good fuel flow.

Sorry, I think the problem is that the carburetor tank is backed up, this happens only if you have a loss in that sector, you will have to see a little gasoline in the sector, you have two gum in the Cuba if any is lazy loses the gasol From the floating very little to take more gasoline, if you give it too much, it would have to work.
