Victa.ducky,

You need one of these to check the carby correctly which is located HERE on the online store.

Have you checked the workshop manual in the spare parts and manuals area for Walbro & Zama carby repair as it will not be easy to try to explain how to fix your problem.

It appears that the needle might not be sealing properly and if so you will need a tooth pick and some valve grinding paste in order to clean the set.

Once you have cleaned the seat you will need to pressure test it with the above tester to see if you have any leaks.
