I have never tried to drill a carb jet. I have read much advice against doing to, so, I buy the bigger size jets and if a jet has been drilled, toss it.
I built a tank tumbler from a BBQ rotisserie motor and gear box. Put sheetrock, decking screws, washers and any other kind of pointy devices I could find intto the fuel tank and tumbled it. Turning the tank to clatter a different area within every day, I made the tumbler so the tank could be pivoted to different positions. Kept that up for about two weeks until that rotisserie unit failed. By then the tank was quite shiny within.
I then rinsed the tank with detergent and hot water. Many rinse outs and detergent and hot water treatments, drying it out with compressed air after each wash/rinse cycle.
Got the bike all together. Running great, for a while, then it started getting sluggish and dying. Checked the spark, timing, all is good.
Off with the carb, dismantled and cleaned it out real good. Back together, not much improved. Back off with the carb, cleaned it out again. About this time I notice a very small bore from the float bowl tank going across, right at the very bottom of the float bowl housing. It was plugged. Cleaned it out thoroughly, along with the jets.
Bike run great, for a short while. That rifling was once again plugged. Cleared it out. Carb back together. Removed the fuel tank. Filled it with apple cider vinegar, shook it up real good every day for about two weeks.
Rinsed the tank out thoroughly and dried it out real well.
There was still a small amount of some kind of particels within. Back in with the vinegar, shook it real well, emptied the vinegar, more detergent and hot water, rinse with more hot water, bloweder dry. Looked mighty clean.
Installed the tank, fired up the motorcicle, little bird runs great now, no more plugging carb and no fuel filter between the tank and the carb.
Oh yeah, save that vinegar. It is mighty handy stuff for cleaning parts and dissolving rust. Pour it back into the jugs and save it.
I have one of those yellow squarish kitty litter buckets in the garage that is filled with apple cider vinegar. When I have parts to clean I hang them in there for several days. Works mighty fine. Even dissolves some of the old paints they used to use back in the day.
