James,
What I want to know is a detailed description on what you have done to the machine so I don't waste time with questions.

1. Did you do anything to the carby. :Wavey:
2. Did you remove the blade plate. :Tweetie:
Please give me step by step things that you have done to the machine as it will be quicker for me to give you a correct answer and even pictures will help as well.
