Make a carb funnel from an old lamp..so simple and easy!
At first you must be sure that the diameter of the lamp is a little longer from your Carb.
1. Take the lamp and cut it in three pieces(look at the photo)
2. You will use the middle piece
3. Find or make a gasket to use between the funnel and the carb
4. Take a sieve and cut it 2mm shorter from the external diameter of your funnel (i used a sieve from an old car speaker)
5. Glue it with silicone (i will find a better way soon)
