Well thanks for that, I've learned something new today. Having googled it I now know what a welch plug is. Sorry, I can't answer your question because I don't know why you would need to remove the said plugs to adjust tick over but I wouldn't have thought so.

Hi Mate, what bike is it? is it a American import? If not then I really wouldn't start mucking about with it, unless your 100% sure you know what you are doing.

Most bikes never need this plug ever removed, and if you muck up getting blanking piece out and damaged the pilot screw underneath, then 99% of the time the carb will be scrap.

It shouldn't really make much difference, unless it's a old American import.

If it is the pilot air screw that has been blanked off then gaining access to it may help to set the idle speed. But as previously stated great care is needed so as not to damage the screw underneath. This procedure is sometimes required with certain Dynojet kits so it is possible.
