Thanks for answering Andy
Unfortunately I have a couple of more questions now.

I have a set of TA22A Carbs and I have 2xJ81E, 2xJ2LB & 2xJ3LC needles.

So from your answer I am assuming I can not use the LB and LC needles in my carbs.

Does that mean I have to find myself a 2QZ needle to have a complete standard Carb setup.

Thanks again for your help
Scott
