Hi all,
I am cleaning the carbs from my barn find. I am using Sean's manual
and everything is going good but I can't seem to clear the slow speed jet on carb 2. Was able to on the other three carbs. Ultrasonic two-thirds times, used the e string (got it down about 1.25 inch).used at least a third of a can carb cleaner. Held my thumb over the primary main jet and my index finger over the lower air cut off hole sprayed down the slow speed but nothing comes out of the pilot screw hole.
As I said the other three I get some carb spray out the pilot screw hole.
Going to tackle it again this weekend any ideas or suggestions would be greatly appreciated. Here's a picture of what came out of that one carb and they were all that nasty lol thanks
