I have seen videos of small engine work where the host used a main jet drill bit kit to either clean or enlarge a carbs main jets. I believe it was a Mikuni kit,which isn't available any more, so I'd like to know if anyone has done this,what did you use and where did you get it? Also I see some thread online where reaming is recommended vs drilling. I have a handful of small main jets that I can upsize to what my needs are now and yes I can easily just buy new one of the sizes needed. I'm looking for info on these main jet drilling sets or an alternative.
