Hi, I was wondering if anyone had any advice on cleaning the carb on an HT73 pole saw. It's sort of a weird carb- unlike any other stihl carb I've seen. It has a primer bulb and no H or L adjustment. My problem is that it totally bogs down and stops like it's not getting any gas when I rev it high or put it under a load. I took it apart, did the carb cleaner thing and put it back together and it won't even start now (it will with some gas directly in the carb). Undaunted, I took it apart again and this time removed the screen, which seemed to have accumulated a bunch of junk on the "back" side (between the screen and the needle valve). Anyway, I thought that was weird but it didn't seem like enough stuff to stop the flow of gas. But what does appear to be plugged (maybe) is the main jet. But I'm not sure how to actually clean it out or if the jet can be removed to be cleaned. Any ideas?
