I have an 80 xl500 that I'm cleaning up the carb. I have all the passages cleared except one. It appears to go from the inlet to the air cutoff valve. It has a brass insert at the inlet and a cast channel to the valve. Right at the bottom of the brass insert it feels blocked, it actually feels like it isn't a hole at all.
The valve still has two other passages to it.
I've tried air and carb cleaner to open it.
My next option is to drill the inlet end.
Wanted some opinions before I do that.
See pics.
At the valve end the other end of the passage lines up with the top right hole in the pic, just above the other hole.
thanks
